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...
