Title: Spin recording method and device
Inventor: MUKASA KOICHI
IPC: H01L21/8246
Filed: 2005-12-28
Abstract: <P>PROBLEM TO BE SOLVED: To form stable bits of atom/molecule scale to significantly improve recording density.  <P>SOLUTION: In an atom (an ion) having an odd number of electrons, the whole spin quantum number S is necessarily half-odd integer. A Kramers dual term remains in a spin Hamiltonian and ±S are in a state of the same energy level when no magnetic field exists. If a magnetic field and a spin magnetic moment are simultaneously reversed, energy does not change due to the time reversal symmetry of the Hamiltonian. Accordingly, in a paramagnetic substance in which the Kramers dual term remains at the lowest energy level of the spin at an extremely low temperature, ±S can be selected by reversing the spin in the magnetic field of lowest energy level, and recording can be made in a state in which no magnetic field exists. This technology records information (signals) by using an isolated spin having such a Kramers dual term.  <P>COPYRIGHT: (C)2007,JPO&INPIT
