BOTTOM SPIN VALVE BASED ON THE ORDERED Ni–Fe–Mn ANTIFERROMAGNETIC PHASE
DOI: 10.17804/2410-9908.2017.6.057-063 Magnetic properties of bilayers based on the Ni–Fe–Mn antiferromagnetic phase are studied, as well as magnetic and magnetoresistive properties of a bottom spin valve (SV) with a Ni–Fe–Mn antiferromagnet as a pinning layer. A technique for the fabrication of bottom spin valves with enhanced thermal stability and improved hysteretic characteristics has been developed. Specimens were made by DC magnetron sputtering and electron-beam evaporation on glass (Corning) and single-crystalline sapphire (1012). For the preparation of bottom SV, the specimens were etched in a PlasmaPro NGP 80 RIE Oxford Instruments reactive ion-plasma etching device. The magnetoresistance of the as-fabricated Al2O3/Ni–Fe–Mn/Co90Fe10(5.5 nm)/Cu(3.6 nm)/Co90Fe10(5.5 nm)/Ta(5 nm) spin valve is DR/Rs = 3.8 %.
