Determination of Crystal and Magnetic Structure of La0,47ca0,53mn1-ycuyo3 (0 < Y < 0.09) Using High Resolution Neutron Powder Diffractometer

Abstract

Crystal and magnetic structure of La0,47Ca0,53Mn1-yCuyO3 with 0 < y < 0.09 at low and room temperature have been analyzes using High Resolution Neutron Powder Diffraction (HRPD). It is obtained that at room temperature as well as at low temperature, the samples have orthorhombic structure with Pnma space group. Increasing x value, will increase the lattice volume. At room temperature, samples have paramagnetic stucture, while at low temperature have antiferromagnetic structure. The value of magnetic moment will decrease with increasing x value
