Abstract
Boron carbide polymers prepared from orthocarborane icosahedra cross-linked with a moiety A wherein A is selected from the group consisting of benzene, pyridine. 1,4-diaminobenzene and mixtures thereof give positive magnetoresistance effects of 30%-80% at room temperature. The novel polymers may be doped with transitional metals to improve electronic and spin performance. These polymers may be deposited by any of a variety of techniques, and may be used in a wide variety of devices including magnetic tunnel junctions, spin-memristors and non-local spin valves.
