被引用回数:1 パーセンタイル:7.51(Materials Science, Multidisciplinary)Temperature dependence of the spin Hall magnetoresistance (SMR) has been investigated herein Pt/CrO/YFeO structure. Well below the Nel temperature of CrO, the SMR is not observed at the noise level of 1.2 ppm. In vicinity of the Nel temperature, only a positive SMR tracks the YIG magnetic switching process, supporting that the SMR of normal metal/antiferromagnetic insulator/ferromagnetic insulator trilayer is controlled by the Nel vector of the antiferromagnetic insulator. A high field magnetoresistance is observed up to an external magnetic field of 20000 Oe which has a field angle dependence symmetry consistent with the SMR. We attribute this high field magnetoresistance to be induced by the Hanle magnetoresistance in Pt.
