Etudes magnetiques et cristallographiques depuis 4, 2K de la solution solide (Ga1−xZnx)Mn3C

Abstract The magnetic and crystallographic measurements were carried on the (Ga 1−x Zn x )Mn 3 C solid solutions as a function of temperature from 4, 2K to 320K. The first order and second order magnetic transformations have been observed as a function of the composition in this metallic perovskites. The phase diagram shows four different ordered magnetic structures.
