INVESTIGATION OF MAGNETIC-PROPERTIES OF C A1-XEUXMNO3 MANGANITES LESS-THAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-0.5)

Magnetic properties of Ca1-xEuxMnO3 perovskites have been studied. The magnetization was observed to increase with the Eu3+ ions substitutin g For those of Ca2+ up to x = 0.1 and then to decrease. The magnetic o rdering temperature increases from 122 K (x = 0) to 140 K (x = 0.2) an d then decreases down to 40 K (x = O.5). The charge ordering takes pla ce at x = 0.2 The charge-ordered phase is supposed to transform From t he antiferromagnetic state to the ferromagnetic one when high magnetic field is applied.
