Abstract:
1. A method to enhance performance of a spintronic device having at least one ferromagnetic layer, comprising: inserting within one or more of said ferromagnetic (FM) layers a magneto-resistance enhancing layer (MREL) comprising a semimetal or semiconductor (S) formed between two conductive layers M1, M2 to give a FM1/M1/S/M2/FM2 configuration where FM1 is a first portion of the at least one FM layer that contacts a lower surface of the MREL, and FM2 is a second portion of the FM layer that contacts an upper surface of the MREL, and M1 and M2 are selected from a group consisting of Cu, Ag, Au, C (including graphene and nano-tubes), Zn, Ti, Sn, Cr, Al, Mg, and Ru.
