According to the Stoner criterion, the density of states at the Fermi level is the crucial factor for the magnetic proximity effect (MPE), implying that the MPE controlled by applying a gate voltage. In this report, we examined the anomalous Hall effect (AHE) in a Pt layer with a small magnetic moment induced by the MPE, and the effect of the gate voltage. We observed a large AHE in CoFe2O4/Pt that could be attributed to the magnetism in Pt induced by the MPE. The AHE magnitude was remarkably changed by −50% to +100% by ion gating.
