Investigation of Low-temperature Magnetic Properties of Rare Earth-based Multiferroic Nanocomposites

Abstract

The magnetic phenomenon of 0.1La0.7Sr0.3MnO3-0.9ErMnO3 and 0.1La0.7Sr0.3MnO3-0.9HoMnO3 multiferroic nanocomposites has been investigated with lowering temperature. The average crystallite size of the nanocomposites was estimated using X-ray diffraction technique. The superparamagnetic nature along with a typical blocking of uncoupled core particle moments is achieved for both the nanocomposites. Moreover, low-temperature surface spin-glass nature occurs at a magnetic field of 200 Oe.
