Abstract

Single phase, polycrystalline mixed rare earth manganite Gd0.5Dy0.5MnO3 (orthorhombic, Pbnm) has been prepared by solid state reaction. Magnetization vs temperature data measured in 100 Oe field shows a weak cusp and a tendency to order around 5 K. Paramagnetic susceptibility shows Curie-Weiss behaviour. Magnetocaloric effect (MCE) has been estimated in terms of isothermal magnetic entropy change (ΔSm). The maximum value of ΔSm is about −13.4 Jkg−1K−1 at 8 K for a field change of 70 kOe.
