Electric Control of the Hall effect in Pt/Bi(0.9)La(0.1)FeO(3) bilayers

Platinum metal, being nonmagnetic and with a strong spin-orbit coupling interaction, has been deposited on weak ferromagnetic Bi(0.9)La(0.1)FeO(3) thin films. The Hall effect is studied as a function of the polarization direction of multiferroic Bi(0.9)La(0.1)FeO(3) thin films, as well as magnetic f...

description Platinum metal, being nonmagnetic and with a strong spin-orbit coupling interaction, has been deposited on weak ferromagnetic Bi(0.9)La(0.1)FeO(3) thin films. The Hall effect is studied as a function of the polarization direction of multiferroic Bi(0.9)La(0.1)FeO(3) thin films, as well as magnetic field (H) and temperature (T). For the two polarization directions, besides the obvious difference of the anomalous Hall resistance R(AH), it increases sharply with decreasing temperature, and even changes sign, thus violating the conventional expression. This observations indicate local magnetic moments in Pt caused by the local electric fields at the interface of Bi(0.9)La(0.1)FeO(3) films. Also, possible proximity effects and induced magnetic ordering in Pt on weak ferromagnetic Bi(0.9)La(0.1)FeO(3) thin films of both upward and downward polarization states may exist and their contribution to the spin-related measurements should not be neglected.
