The magnetocaloric effect (MCE) and electric-dielectric properties of the Nd-cobaltate perovskitesNd0.6Sr0.4Co1xMnxO3(x = 0, 0.3, 0.7 and 1) were investigated for possible use in magnetic cooling appli-cations. Upon Mn substitution, the magnetic exchange interaction is affected by the (Mn4+/Mn3+) ratio,which in turn impacts several physical properties. The XRD patterns of the synthesized compositesrevealed a single phase with an orthorhombic structure with ... Read more
