Abstract

We have successfully developed new RuRhMn antiferromagnetic (AF) films for spin-valves. The spin-valves with RuRhMn exhibit larger unidirectional anisotropy (Hua), higher blocking temperature (Tb), higher thermal stability and higher corrosion resistance than those with FeMn films. The MR ratio of 7.4% and Tb of 250°C are obtained for glass/Ta(5)-NiFe(7)-Co(0.5)-Cu(3)-Co(2.5)-RuRhMn(10)-Ta(5), unit ran, spin-valve with Hua of 350 Oe. The rest potential of RuRhMn films is listed between one of NiFe and Co films and much better than one of FeMn films.
