| Summary:
We study temperature dependence of spin Hall magnetoresistance (SMR) in
antiferromagnetic insulator (AFI)/metal bilayer systems. We calculate the
amplitude of the SMR signal using the quantum Monte Carlo simulation and
examine how the SMR depends on the amplitude of the spin, thickness of the AFI
layer, and randomness of exchange interactions. Our results for simple quantum
spin models provide a useful starting point for understanding of the SMR
measurement for atomic layers of magnetic compounds.
