Pr0.7 Ca0.3 Mn1-x Ax O3 (A= Ru, x= 0; 0,05; 0,1; 0,15; 0,2; 0,3; 0,5 ) determination of structural, magnetiv and magnetocaloricproperties of samples

In this study, the effects of Ru doping on structural, magnetic and magnetocaloric properties of Pr0.7 Ca0.3 Mn1-x Ax O3 (A= Ru, x= 0; 0,05; 0,1; 0,15; 0,2; 0,3; 0,5 ) samples were investigated. It was observed that all the samples had orthorhombic symmetry, although there was no significant change in the X-ray structure analyzes of all the samples doped with Ru instead of Mn. The decrease in Curie temperature and saturation magnetization with Ru content could be due to reduced ferromagnetic effect in Ru -doped compounds. The decrease in magnetic entropy change could be due to the reduction in saturation magnetization with increasing Ru content. It was observed from the drawn arrott graphs that the samples were in binary phase.
