Magnetic anisotropy (MA) is one of the most important material properties for modern spintronic devices. Conventional manipulation of the intrinsic MA, i.e., magnetocrystalline anisotropy (MCA), typically depends upon crystal symmetry. Extrinsic control over the MA is usually achieved by introducing shape anisotropy or exchange bias from another magnetically ordered material. Here we demonstrate a pathway to manipulate MA of 3d transition-metal oxides (TMOs) by digitally inserting nonmagnetic 5d TMOs with pronounced spin–orbit coupling (SOC). High-quality superlattices comprising ferromagnetic La2/3Sr1/3MnO3 (LSMO) and paramagnetic SrIrO3 (SIO) are synthesized with the precise control of thickness at the atomic scale. Magnetic easy-axis reorientation is observed by controlling the dimensionality of SIO, mediated through the emergence of a novel spin–orbit state within the nominally paramagnetic SIO.

In Si–La0.7Sr0.3MnO3, the interfacial charge transfer driven strong localized antiferromagnetic and spin–orbit couplings favor positive magnetoresistance, which is suppressed by strong magnetic scattering induced by the top ZnO layer results in negative magnetoresistance.

Perovskite SrRuO3 is a unique 4d transition metal oxide with coexisting spin-orbit coupling (SOC) and electron-electron correlation. However, intrinsic, non-reconstructed surface structure of SrRuO3 has not been reported so far....

The complete active space self-consistent field/internally contracted multireference configuration interaction calculations with the correlation-consistent basis sets have been made to characterize all of the states of BeAr+ cation, which are attributed to the first two dissociation channels. The effect on the potential energy curves by Davidson correction, core-valence correlation, and scalar relativistic corrections is included. The spin-orbit coupling effect is taken into account by the state interaction method with the Breit–Pauli Hamiltonian. Our calculations can provide some useful guidelines for the future experimental work of band system 22[Formula: see text]+1/2-X2[Formula: see text]+1/2. For the first time, the transition properties including Franck−Condon factors and transition dipole moments have been derived for all of the Ω states. Some transition probabilities and radiative lifetimes have been estimated.
