Metal-insulator transition, specific heat, and grain-boundary-induced disorder in Sm0.55Sr0.45MnO3

The effects of the grain-boundary-induced lattice disorder on the resistivity, the magnetization, and the specific heat of a prototypical manganite Sm0.55Sr0.45MnO3 near half doping were investigated at temperatures near the metal-insulator transition. An increasing lattice disorder softens the magnetic phase transition from a first order phase transition into a second order transition. Furthermore, the peaks in the resistivity and specific heat are broaden and there is an increase in the charge-carrier scattering rates in the metallic and insulating states. The origin of these phenomena is discussed.
