We have studied the effect of Fe substitution on magnetic and magnetocaloricproperties in La0.7Sr0.3Mn1-xFexO3 (x = 0.05, 0.07, 0.10, 0.15, and 0.20) overa wide temperature range (T = 10-400 K). It is shown that substitution by Fegradually decreases the ferromagnetic Curie temperature (Tc) and saturationmagnetization up to x = 0.15 but a dramatic change occurs for x = 0.2. The x =0.2 sample can be considered as a phase separated compound in which bothshort-range ordered ferromagnetic and antiferromagnetic phases coexist. Themagnetic entropy change (DSm) was estimated from isothermal magnetizationcurves and it decreases with increase of Fe content from 4.4 J/KgK at 343 K (x= 0.05) to 1.3 J/KgK at 105 K (x = 0.2), under H = 5 T. TheLa0.7Sr0.3Mn0.93Fe0.07O3 sample shows negligible hysteresis loss, operatingtemperature over 60 K range around room temperature with refrigerant capacityof 225 J/Kg, and magnetic entropy of 4 J/kgK which will be an interestingcompound for application in room temperature refrigeration.
