| Abstract Scope |
The family of perovskite oxides display intriguing functional properties with applications in emerging fields such as neuromorphic and spintronic applications due to their strong interactions between the charge, spin, lattice, and orbital degrees of freedom. In this talk, I will provide an overview of our recent results on the La<sub>0.67</sub>Sr<sub>0.33</sub>CoO<sub>3</sub> (LSCO)/La<sub>0.67</sub>Sr<sub>0.33</sub>MnO<sub>3</sub> (LSMO) system where interfacial interactions can be harnessed to achieve emerging functionality not found in the constituent materials. The LSCO/LSMO interface was characterized by a soft LSCO layer with magnetically active Co<sup>2+</sup> ions which formed due to the combined effect of the formation of oxygen vacancies and interfacial charge transfer. The nature of the interfacial interactions could be carefully controlled with factors such as the LSCO layer thickness, epitaxial strain, and the layer stacking order. These results highlight the versatility of perovskite oxide heterostructures to tailor magnetic interactions for next generation information technology devices. |
