Strain dependent magnetocaloric effect in La0.67Sr0.33MnO3 thin-films

Strain dependent magnetocaloric effect in La0.67Sr0.33MnO3 thin-films

The strain dependent magnetocaloric properties of La0.67Sr0.33MnO3 thin films deposited on three different substrates (001) LaAlO3 (LAO), (001) SrTiO3 (STO), and (001) La0.3Sr0.7Al0.65Ta0.35O9 (LSAT) have been investigated under low magnetic fields and around magnetic phase transition temperatures....
