Abstract

An unambiguous antiferromagnetic interlayer exchange coupling (IEC) is realized in all-perovskite oxide La_0.7Sr_0.3MnO₃(LSMO)/SrRu_1-_xTi_xO₃(SR_1-_xT_xO) (x < 0.3) superlattices above the Curie temperature of the SR_1-_xT_xO spacer layer, which is different from the traditional interfacial antiferromagnetic coupling. For 0.3 ≤ x ≤ 0.5, the superlattices behave as a ferromagnetic coupling. Meanwhile, this antiferromagnetic IEC between the ferromagnetic LSMO layers across the SR_1-_xT_xO spacer can be further modulated by changing the thickness of SR_1-_xT_xO spacer. Combining the high Curie temperature of LSMO, these findings may have potential applications in future spintronic devices.
