“…The gradual phase shift observed in all rotational directions is remarkable and suggests a modulation of the effective magnetic anisotropy with increasing temperature. Suppression of specific anisotropy axes may arise due to possible temperature-dependent structural properties such as polar order or strain similar to that reported in strained manganites such as La 0.67 Sr 0 .67MnO 3 , where a strong temperature dependence of the magnetocrystalline anisotropy is observed [43,44].…”

Multiferroics have found renewed interest in topological magnetism and for logic-in-memory applications. Among them, SrMnO 3 , possessing strong magnetoelectric coupling, is gaining attention for the design of coexisting magnetic and polar orders upon straining. Here we demonstrate antiferromagnetic exchange interactions in strained SMO thin films extracted from a new feature in the phase response of spin Hall magnetoresistance, which has not been explored in earlier works, such as in magnetic insulators. We explain our findings with a model that incorporates magnetic anisotropy along the [110] direction, corroborates with density functional theory studies, and is consistent with the direction of ferroelectric polarization in SrMnO 3 . The fundamental insights obtained from our studies establishes the potential of this material in magnetoelectrically coupled devices for different logic and memory applications.

“…The emergence of the fourfold oscillations indicates the competition of multiaxial anisotropies in single SRO and SS1 films. We fitted the fourfold oscillations using a phenomenological model, which is widely used to describe the MR [30][31][32] in crystalline systems (fitting details can be found in the supplementary material). The fitting is used to extract the evolution of the amplitude of R xx , from where we found that the largest fourfold signal in single SRO is at 120 K at an applied field of 1, and at 115 K in SS1 for the same magnetic field.…”

Tunability of magnetic anisotropy in perovskite oxides, such as in SrRuO3, is commonly achieved by controlling the octahedral distortion through strain. Here, we demonstrate that differences in the oxygen vacancies at the heterointerface of SrMnO3/SrRuO3 can also strongly influence the magnetocrystalline anisotropy in SrRuO3 despite being fully strained by the underlying substrate. Modification of the spin–orbit coupling strength by altering the hybridization of Ru-4d and O-2p orbitals in SrRuO3 leads to a clear evolution of the magnetocrystalline anisotropy from multiaxial to strongly out-of-plane, as manifested in the magneto-transport studies. Our results provide an alternative design strategy for their incorporation in practical spintronic devices for memory and computing applications and operation by spin–transfer and spin–orbit torques.

Spin–orbit coupling and breaking of inversion symmetry are necessary ingredients to enable a pure spin current-based manipulation of the magnetization via the spin–orbit torque effect. Currently, magnetic insulator oxides with non-dissipative characteristics are being explored. When combined with non-magnetic heavy metals, known for their large spin–orbit coupling, they offer promising potential for energy-efficient spin-orbitronics applications. The intrinsic electronic correlations characterizing those strongly correlated oxides hold the promises to add extra control-knobs to the desired efficient spin-wave propagation and abrupt magnetization switching phenomena. Spinel vanadate FeV2O4 (FVO) exhibits several structural phase transitions, which are accompanied by an intricate interplay of magnetic, charge, and orbital orderings. When grown as a thin film onto SrTiO3, the compressive strain state induces a perpendicular magnetic anisotropy, making FVO-based heterostructures desirable for spin-orbitronics applications. In this study, we have optimized the deposition of stoichiometric and epitaxial Pt/FVO heterostructures by pulsed laser deposition and examined their spin-related phenomena. From angle-dependent magnetotransport measurements, we observed both anisotropic magnetoresistance and spin Hall magnetoresistance (SMR) effects. Our findings show the SMR component as the primary contributor to the overall magnetoresistance, whose high value of 0.12% is only comparable to properly optimized oxide-based systems.
