Effect of Eu Doping on the Structural, Magnetic and Magnetocaloric Properties in La0.85Ag0.15MnO3

In this research, the effect of Eu doping on the structural, magnetic and magnetocaloric properties in La0.85Ag0.15MnO3 sample synthesized by sol-gel technique has been studied. The structural analysis show that crystal structure of the sample is found as rhombohedral being the same as undoped sample. But, the average particle size decreases when Eu is doped in the main structure. In the magnetic analysis, a magnetic transition is observed from ferromagnetic to paramagnetic phase around 192 K. The maximum magnetic entropy change (−ΔSM)max and relative cooling power (RCP) values were found as 2.78 J/kgK and 142.31 J/kg under 5 T field change.
