  We study the anomalous Hall-like effect (AHLE) and the effective anisotropic
magnetoresistance (EAMR) in antiferromagnetic {\gamma} -IrMn3/Y3Fe5O12(YIG) and
Pt/YIG heterostructures. For {\gamma} -IrMn3/YIG, the EAMR and the AHLE
resistivity change sign with temperature due to the competition between the
spin Hall magnetoresistance (SMR) and the magnetic proximity effect (MPE)
induced by the interfacial antiferromagnetic uncompensated magnetic moment. In
contrast, for Pt/YIG the AHLE resistivity changes sign with temperature whereas
no sign change is observed in the EAMR. This is because the MPE and the SMR
play a dominant role in the AHLE and the EAMR, respectively. As new types of
galvanomagnetic property, the AHLE and the EAMR have proved vital in
disentangling the MPE and the SMR in metal/insulating-ferromagnet
heterostructures.
