Interfacial orbital preferential occupation induced controllable uniaxial magnetic anisotropy observed in Ni/NiO(110) heterostructures

Condensed matter physics: unexpected magnetic anisotropy emerges in a heterostructure An unexpected magnetic anisotropy emerges at the interface of nickel and nickel oxide, which is attributed to the anisotropic orbital occupation of interfacial nickel ions. A team led by Yuan-Hua Lin at the Tsinghu...
