AB - Negative magnetization phenomenon is an unusual magnetic behavior where magnetic ordering temperature of two or more types of constituent magnetic moments are believed to be different. This magnetization crossover from positive to negative at low temperatures has triggered interest due to its futuristic potential applications in spintronics. In the present article, our experimental and theoretical results manifest the magnetization reversal in nanocrystalline Gd0.5Sr0.5MnO3 compounds, while this intrinsic effect of negative magnetization is absent in the bulk form. We argue that the antiferromagnetic interactions between Gd sublattice and Mn sublattices increases with decreasing particle size of the Gd0.5Sr0.5MnO3 compound as we go from bulk to nanocrystalline compounds and hence exhibits the negative magnetization in nanocrystalline compounds at low temperatures. We implement Monte Carlo simulation based on classical Heisenberg model supplemented by magnetocrystalline anisotropy to emphasize the key role of this antiferromagnetic interaction among Gd and Mn sublattices by systematically studying negative magnetization.
