Description

Polycrystalline CdMnS and CdMnS: Au films with hexagonal structure on Si(111) substrates are prepared by co-evaporation, and exhibit ferroelectric and ferromagnetic properties, respectively Under optimized growth conditions, CdMnS: Au samples with an average crystallite size of 90 nm and Mn concentration of 5.0 at. % are obtained, and an all-semiconductor spin valve device of Co/Au/CdMnS: Au/CdMnS/Pt is fabricated. Electrical measurement of the device reveals the clear dependence of resistance on applied magnetic field, with a relative magnetoresistance of 0.06% and a switching field of 100 Oe at 77 K.
