Magnetic proximity effect has only been conclusively observed in ferromagnet-based systems. We report the observation of anomalous Hall effect and angular-dependent anisotropic magnetoresistance in Pt on antiferromagnetic (0001) epitaxial films at 10 K, which provide evidence for the magnetic proximity effect. The Neel order of and the induced magnetization in Pt show a unique angular-dependent magnetoresistance compared with all other ferromagnetic and antiferromagnetic systems. In conclusion, a macrospin response model is established and can explain the antiferromagnetic spin configuration and all main magnetoresistance features in the bilayers.
