Room-temperature magnetic entropy change in La0.7Sr0.3Mn1-xMxO3 (M = Al, Ti)

Magnetic entropy change in and above the room‐temperature region has been measured for La0.7Sr0.3Mn1‐x Mx O3 (M = Al, Ti) by means of magnetization measurements in magnetic fields up to 6 T. The magnetocaloric effect (MCE) becomes strongest at the Curie temperature Tc that is tuned to ∼300 K by the...
