Abstract
Magnetization and crystal structure of Eu1-xCaxMnO3 (0≤x≤1) perovskite have been studied. It is shown that these compounds can be divided into four concentration regions in which different magnetic phases coexist. The antiferromagnetic phases are associated with the regular arrangement of Mn3+ and Mn4+ ions in ratios 1:0, 1:1, 1:3 and 0:1 respectively. The ferromagnetic phases are attributed to the charge disordered states and arise in 0≤x≤0.4 and 0.8≤x≤1 concentration regions. The samples x=0.8 and 0.85 show metamagnetic behavior which might result from destruction of the charge ordered (1:3) state.
