Abstract

The polycrystalline samples (La_1−xNd_x)_2/3(Ca_1−ySr_y)_1/3MnO₃ were prepared by the solid-state reaction method. Magnetization measurements versus temperature were performed in order to investigate the magnetic properties such as the metamagnetic transition. The transition temperature estimated from the maximum of dM/dH is found sensitive to disorder σ² leading to the formation of an inhomogeneous metastable state and to subsequent magnetization jumps. The peak temperature coefficient of the resistivity improved significantly from 1.54 to 8.21% K⁻¹ due to the increase in disorder. These findings suggest that (La_1−xNd_x)_2/3(Ca_1−ySr_y)_1/3MnO₃ ceramics can be used to prepare uncooled infrared bolometers.
