Fig. 3From: The Magnetic Susceptibility Bifurcation in the Ni-Doped Sb2Te3 Topological Insulator with Antiferromagnetic Order Accompanied by Weak Ferromagnetic AlignmentThe magnetic susceptibility of field cooled and zero-field cooled processes at different external magnetic fields. The magnetic susceptibility of field cooled and zero-field cooled coincides above 125 K and bifurcates below 125 K. A larger magnetic susceptibility splitting at lower external magnetic fields and temperatures. No more magnetic susceptibility splitting is observed at magnetic field above 7000 Oe.
