Talk:Spintronics

message: In the Wikipedia article for Graphene (in the "Electronic properties" section), it is mentioned "Intrinsic graphene is a semi-metal or zero-gap semiconductor." I had no idea what "zero gap" meant but I deduce it is a part of spintronics theory. This link  seems to be on the topic. It would be nice if there was a section in Spintronics about "zero gap" stuff and it was then linked from Graphene at the mention of "zero gap" to the zero gap section we make in Spintronics.

replies: text: Disagree: Zero-[energy]-band gap materials are not specific to spintronics and IMO graphene should not be linked here as you suggest. 'Zero-gap' could be explained in band gap or semimetal. - Rod57 (talk) 12:23, 30 March 2020 (UTC)

message: In the upper-right "Unsolved problems" box, I had changed the link to charge to link to electric charge in order to disambiguate.  May I get some opinions on whether or not that was correct?  A user changed it back, but did not explain why. Aguerriero (talk) 22:53, 13 June 2006 (UTC)

thread_title:  Question on disambiguation 

message: I came up with this TeX for the GMR ratio:
\frac{\left (Antiparallel~Resistance - Parallel~Resistance\right )}{Parallel~Resistance} \times 100\%
But I'm not sure whether it can fit inside the article. It is probably better than the present representation, the plain text "(Antiparallel Resistance - Parallel Resistance) / Parallel Resistance x 100%", but it doesn't fit in line.  — Itai (talk) 17:08, 8 August 2006 (UTC)

message: List of NAS manufacturers mentions "Spintronics" and links here.
Is there really a "Spintronics" company that sells NAS systems?
My Google search is finds only references to the physics concept, not any company.

replies: text: There's an "Applied Spintronics Inc." in the MRAM business, and a free energy scam called "Spintronics, Inc." but I don't find any such current company making Network Attached Storage. However, many disk drives do have giant magnetoresistance heads, so there is a bit of overlap... LeadSongDog come howl! 15:13, 9 October 2015 (UTC)
thread_title:  the other Spintronics 

message: The first paragraph of the main article seems very badly worded to me. Why is there a segue into talking about unrelated properties of electrons? And isn't spin a general property of fermions, not just electrons? Wouldn't the concept of 'spintronics' also incorporate this? 314159 00:03, 20 July 2007 (UTC)
thread_title:  Re-write needed? 

message: I suggest that the effects of spin Coulomb drag (or spin drag, for short) as predicted in 2000 by Giovanni Vignale and Irene D'Amico of the University of Missouri - Columbia, and confirmed in 2005 by Joseph Orenstein et alia of the Lawrence Berkeley National Laboratory, be discussed in this article.--Corkgkagj 22:43, 2 December 2007 (UTC)
thread_title:  Spin Coulomb Drag 

message: 
This does not belong here. Unresolved problems are reserved for fundamental problems, not about problems about how to develop something to the practical state. Likewise a space elevator isn`t a fundamental physical problem either. It might fit in a e.g. "hot topic" template.Slicky (talk) 08:39, 1 February 2008 (UTC)
thread_title:  Removed the unresolved problem 

message: This spintronics page is in need of a major round of edits. In particular, it does not address the profound difference between spin transport in metals and semiconductors, and the particular challenges with spin injection and detection in the latter. The only mention of "semiconductor" is in the context of ferromagnetic semiconductors like GaMnAs. There are also several inaccurate/misleading statements in need of correction (including historical origins of the field), and more recent review references should be updated. Please respond to this post if you have any specific suggestions on topics; I intend to start work on this in the next few weeks but want others to have the opportunity to comment before I begin.

message: Can someone review the first "Applications" section?  It reads like a mix of OR, description of the future and assumption. Needs sourcing, citing, and some strict cleanup. FT2 (Talk | email) 17:14, 23 September 2008 (UTC)

thread_title:  Repeated vandalism 

message: DNA puts a new spin on electrons says "Spintronics holds great promise for creating circuits that are faster and more energy efficient than standard semiconductor devices. This is because the energy required to transport and process spins is much less than that needed to create electron currents. "  Should we add something like this to the intro ?  And is the DNA spin filter worth mentioning ? Rod57 (talk) 01:05, 18 February 2011 (UTC)
thread_title:  Potential and DNA spin filters 

message: The emphasis of the theory section is on explaining some of the mathematics of spin and the magnetic moment of the electron, but the part at the very end about non-equilibrium spin populations is the fundamental issue and should be expanded.  The theory should give a cursory explanation of orbital and spin moments, linking to the article on spin for a detailed discussion.  A graphic would be very useful in this section.  — Preceding unsigned comment added by Infinitooples (talk • contribs) 22:24, 6 January 2012 (UTC)
thread_title:  Theory section needs a rewrite 

message: The section contains this sentence: A net spin polarization can be achieved either through creating an equilibrium energy split between spin up and spin down.  The word "either" isn't followed by an "or". Also, I can't tell if the word "split" is part of a noun phrase "equilibrium energy split". Here's a different reading: the noun phrase is only two words "equilibrium energy", and the word "split" begins a clause: "split between spin up and spin down". The sentence needs rewriting. To do so, the editor should have both good knowledge of the subject and strong grammatic skills. Oaklandguy (talk) 17:16, 23 July 2020 (UTC)

thread_title:  Finding more literature on spintronics 

message: I recently learned of spin caloritronics, and I'm not sure if its a subset of spintronics, just a different name for the same field, or something new. Here's an article about it: https://www.sciencedaily.com/releases/2015/09/150923083429.htm . I'd appreciate some feedback from someone in the know.

message: In 2022 (maybe 2021), the company Upper Story released a toy named Spintronics, to teach kids electronics concepts with mechanical analogues. This is not related to the field of spintronics. 2601:1C2:801:580:3D35:51A7:F246:2002 (talk) 16:34, 18 August 2023 (UTC)
