Abstract:We investigate the structural, magnetic and spin-state transitions, and magnetocaloric properties of Sr2−xLaxCoNbO6 (x = 0-1) double perovskites. The structural transition from tetragonal to monoclinic phase at x 0.6, and an evolution of (101)/(103) superlattice reflections and Raman active modes indicate the enhancement in the B-site ordering with x. The magnetic susceptibility data reveal the transition from weak ferromagnetic (FM) to antiferromagnetic (AFM) ordering for x 0.6 with TN≈9-15 K. Interestingly, … Show more
