Structural, optical and magnetic investigation of the novel double perovskite La2FeCuO6 for hydrogen energy conversion application

In this study, we investigate the structural, optical, magnetic, and electrocatalytic properties of the double perovskite La2FeCuO6, synthesized via a conventional solid state reaction method. Structural analysis based on X-ray diffraction and Rietveld refinement reveals a predominantly monoclinic P21/n phase (93.8%) w...

Evidence for Isostructural Magnetoelastic Coupling across the Magnetic Transition in Disordered NdSrCoFeO6–δ

Disordered double perovskites offer a rich interplay between chemical disorder, magnetic frustration, and lattice degrees of freedom, yet the role of the average crystal structure in mediating magnetic transitions remains poorly understood. Here, we report a magnetoelastic lattice-strain anomaly in the B-site-disorde...
