Magnetic and Resistive Properties of Magnetite/Iridate Heterostructures
- 43 Downloads
A technique is developed to grow epitaxial heterostructures consisting of strontium iridate (SrIrO3) and lanthanum–strontium manganite (La0.7Sr0.3MnO3). Their transport properties and ferromagnetic resonance spectra are measured. The parameters obtained are compared with the properties of individual iridate and manganite films. The results of resistive measurements point to conduction of the iridate/manganite interface. As temperature decreases, the ferromagnetic resonance line width increases and the resonance field decreases, which indicates the appearance of additional ferromagnetic ordering in the heterostructures.
