Title: Influence of chemical composition and crystallographic orientation on the interfacial magnetism in $BiFe O_{3}$ / $L a_{1 - x} S r_{x} Mn O_{3}$ superlattices

Abstract

The emergence of magnetism unique to the interface between the multiferroic BiFeO ₃ (BFO) and ferromagnetic La _1-xSr _xMnO ₃ (LSMO) offers an opportunity to control magnetism in nanoscale heterostructures with electric fields. Here, we investigate the influence of chemical composition and crystallographic orientation on the interfacial magnetism of BFO/LSMO superlattices. Our results reveal that the induced net magnetic moment in the BFO layers increases monotonically with increasing saturation magnetization of the LSMO layers. For the (100)-BFO/LSMO (x=0.2) superlattice, the induced moment reaches a record high value of ~2.8μ _B/Fe. No interfacial magnetization is observed at the (100)-BFO/LSMO interface when LSMO is an antiferromagnet. In contrast to (100)-oriented superlattices, no induced moment is observed in (111)-BFO layers. Our results suggest the interfacial structural reconstruction may not be a sufficient condition for the enhanced net moment in BFO layer. Instead, spin canting induced by interfacial exchange coupling is proposed in the (100)- but not in the (111)-BFO, leading to the large net magnetization at the (100)-oriented interface. Lastly, this work further demonstrates the importance of exchange coupling across heterointerfaces for spin canting in nominally antiferromagnets, providing a pathway to control the magnetic properties of artificial oxide heterostructures.

Journal Article Wang, Wei ; Zhang, Jine ; Shen, Xi ; ... - Physical Review B

Perpendicular magnetic anisotropy (PMA) in multilayer thin films promotes the development of spintronic and magnonic research fields. The origin of the PMA deserves a thorough investigation since it contains rich physics related to multiple factors in the heterostructure system. In this report, we study the origin of PMA in La _2/3Sr _1/3 Mn O ₃ (LSMO) thin films sandwiched by La _1-xSr _xCoO _3-δ (LSCO) layers grown on SrTiO ₃ substrate, using aberration-corrected scanning transmission electron microscopy. Our findings indicate that the lattice and electronic structures of LSMO can be modified through the inhomogeneous strains induced by nanodomains in LSCOmore »« less

Evolution of magnetism in single-crystal $C a_{2} R u_{1 - x} I r_{x} O_{4} (0 \leq x \leq 0.65)$

Journal Article Yuan, S. J. ; Terzic, J. ; Wang, J. C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

In this paper, we report structural, magnetic, transport, and thermal properties of single-crystal Ca ₂Ru _1-xIr _xO ₄(0≤x≤0.65). Ca ₂RuO ₄ is a structurally driven Mott insulator with a metal-insulator transition at T _MI=357K, which is well separated from antiferromagnetic order at T _N=110K. Substitution of a 5d element, Ir, for Ru enhances spin-orbit coupling and locking between the structural distortions and magnetic moment canting. Ir doping intensifies the distortion or rotation of Ru/IrO ₆ octahedra and induces weak ferromagnetic behavior along the c axis. In particular, Ir doping suppresses T _N but concurrently causes an additional magnetic ordering Tmore »« less

Controlling entangled spin-orbit coupling of $5 d$ states with interfacial heterostructure engineering

Journal Article Kim, J. -W. ; Choi, Y. ; Chun, S. H. ; ... - Physical Review B

Here, the combination of strong electron correlations in 3d transition metal oxides and spin-orbit interactions in the 5d counterpart can give rise to exotic electronic and magnetic properties. Here, the nature of emerging phenomena at the interface between SrIrO ₃ (SIO) and La _2/3Sr _1/3MnO ₃ (LSMO) is presented. Nominally, SIO with strong spin-orbit interaction is metallic and nonmagnetic on the verge of a metal-insulator transition, whereas LSMO is metallic and ferromagnetic with itinerant character and high spin polarization. In the 1:1 LSMO/SIO superlattice, we observe ferromagnetic Mn moments with an insulating behavior, accompanied by antiferromagnetic ordering in SIO. Element-resolvedmore »« less

Using a classical Heisenberg model with anisotropic nearest-neighbor superexchange and uniaxial anisotropy, I investigate the magnetic order of the transition metals on the B sites in AMn _1-xFe _xO ₃(A=La, Nd; x=[0,1]) with Monte Carlo methods. Magnetic parameters are extracted from preexisting experimental data when available and otherwise estimated with calculations. Superexchange energies are compared to density functional theory and anisotropy energies to ligand field theory, and the potential for doping-induced strain affecting these parameters is considered. I find coexistence regions of different types of magnetic order (A-type and G-type antiferromagnetism), regions with distinct magnetic transitions for the two ordermore »« less
