Abstract
The structural and magnetic ordering in La0.6Ca0.4MnO3 has been studied by neutron powder diffraction as a function of temperature between 15 and 300 K. The para-ferromagnetic transition at T similar to 250 K is accompanied b y significant structural distortions in the form of octahedral Mn-O-6 rotat ions. At 15 K, the total refined ferromagnetic moment on the Mn site was ob tained as 3.1 mu (B), in reasonable agreement with the total expected avera ge moment of mixed Mn3+/Mn4+ matrix.
