We use computational and experimental methods to study d(0) ferromagnetism at a charge-imbalanced interface between two perovskites. In SrTiO(3)/KTaO(3) superlattice calculations, the charge imbalance introduces holes in the SrTiO(3) layer, inducing a d(0) ferromagnetic half-metallic 2D hole gas at the interface oxygen 2p orbitals. The charge imbalance overrides doping by vacancies at realistic concentrations. Varying the constituent materials shows ferromagnetism to be a general property of…

Multiferroic interfaces composed of d0 perovskites oxides

We investigate the electronic, ferroelectric and magnetic properties of KTaO3/PbTiO3 interfaces by using conventional density functional theory (DFT) and advanced DFT such as hybrid functional HSE06.

Magnetoelectric effects at the interfaces between nonmagnetic perovskites: Ab initio prediction

A novel mechanism of magnetoelectric coupling at the KTaO3/BaTiO3 interfaces composed of nonmagnetic ferroelectric insulators is studied by density functional theory methods. We show that holes

High mobility half-metallicity in the (LaMnO3)2/(SrTiO3)8 superlattice

First principles calculations have been performed to investigate the LaMnO3/SrTiO3 superlattice. Structural relaxation within the generalized gradient approximation results in no significant tiltings

Ab initio study of the p-hole magnetism at polar surfaces of ZnO: the role of correlations

It is demonstrated that partially filled oxygen p orbitals of the polar surfaces exhibit magnetic moment formation and long range magnetic order leading to the occurrence of a ferromagnetic ground state in polar oxygen-terminated ZnO surfaces.

Magnetic hysteresis behavior and magnetic pinning in a d0 ferromagnet/superconductor nanostructure

We investigate the interaction between superconductivity and defect-induced d0 ferromagnetism using a composite consisting of MgB2 and MgO nanocrystals. The composite exhibits a ferromagnetic

The effect of oxygen vacancy on holes-induced d0 magnetism in CaTiO3 and CaZrO3

Using the first-principles calculations, the holes-induced d0 magnetism associated with oxygen vacancy (VO) in CaTiO3 and CaZrO3 has been investigated. To obtain holes, the divalent calcium and

Collective magnetic response of inhomogeneous nanoisland FeNi films around the percolation transition

By using superconducting quantum interference device (SQUID) magnetometry, we investigated anisotropic high-field (H ≲ 7T) low-temperature (10 K) magnetization response of inhomogeneous nanoisland
