研制了一种以钙钛矿型反铁磁体MFeO/sub 8/（M=Y，La，Pr，Nd，Sm）为钉扎层的新型自旋阀。这些自旋阀由MFeO/sub 8//P/Cu/F组成，其中P和F分别是钉扎层和自由层，并且通过溅射在Si或玻璃衬底上制备。在这些自旋阀中，LaFeO/sub 3//CoFe/Cu/CoFe在室温下显示出大的MR比（11.4%），并且即使在350/spl deg/C下退火后MR比也是稳定的。
A new type of spin-valves using perovskite antiferromagnets, MFeO/sub 8/ (M=Y,La,Pr,Nd,Sm), as the pinning layers was developed. These spin-valves are composed of MFeO/sub 8//P/Cu/F, where P and F are the pinned and free layers, respectively, and were prepared by sputtering on Si or glass substrates. Among these spin-valves, LaFeO/sub 3//CoFe/Cu/CoFe showed large MR ratios, 11.4%, at RT and the MR ratios were stable even after the annealing at 350/spl deg/C.
