Temperature-dependent magnetotransport properties of CoFe₂O₄/Pt heterostructure

We report on the growth of CoFe₂O₄/Pt heterostructure and their magnetotransport properties. The magnetoresistance under high magnetic fields exhibits a sign change when the temperature increases from 5 K to 10 K. The anomalous Hall resistance decreases as the temperature increases. Furthermore, angle-dependent magnetoresistance indicates that the observed magnetotransport behaviors originate from the competition between the spin Hall magnetoresistance and magnetic proximity effect.
