  • The authors report magnetotransport evidence for the coexistence of a two-dimensional (2D) superconducting state and a 2D ferromagnetic state at the interface between amorphous CaZrO3 film and KTaO3 single crystal. Moreover, the magnetoresistance hysteresis reaches a maximum near the superconducting transition temperature.

  • Perovskite oxides, when combined into heterostructures and superlattices can yield emergent properties not present in the constituent components. Here, by combining LaNiO3, a Pauli paramagnetic material, with LaFeO3, an antiferromagnetic insulator, Zhou et al create a strongly ferromagnetic superlattice with a Curie temperature of over 600 K.

  • In this paper, we report the dimensional control of the interface coupling-induced ferromagnetic phase in perovskite-CaRuO3/infinite-layered-SrCuO2 superlattices. The Hall and magnetoresistance measurements indicate the appearance of an interfacial ferromagnetic state in the originally paramagnetic CaRuO3 layers when the CaRuO3 layer is in proximity to the chain-type SrCuO2 layers; this superlattice has the highest Curie temperature of ~75 K and perpendicular magnetic anisotropy. Along with the thickness-driven structural transition from chain-type to planar-type of the SrCuO2 layers, the interfacial ferromagnetic order gradually deteriorates and finally disappears.
