Crossover from charge order to strain glass in phase separated manganite thin films: Impact of thermal cycling and substrate induced strain
No full textImpact of substrate on magnetic phase coexistence in bicritical Sm0.53Sr0.47MnO3 thin films
No full textSm0.53Sr0.47MnO3 thin films were deposited on single crystal LaAlO3 (LAO/(001)) and SrTiO3 (STO/(001)) substrates by DC magnetron sputtering. The theta-2 theta and omega-2 theta scans show that these films have very good crystallinity and the films on LAO and STO are under compressive and tensile strain, respectively. The films on LAO and STO substrates show ferromagnetic (insulator-metal) transition at T-C similar to 126 K (at T-IM similar to 128 K) and 120 K (T-IM similar to 117 K), respectively. The magnetic state at T < T-C is akin to cluster glass, which is formed by the presence of charge ordered-antiferromagnetic clusters in the ferromagnetic matrix. Huge drop in the resistivity at T-IM and the associated hysteresis with respect to cooling and warming cycles reveal the bicritical and the first order nature of phase transition, which is also confirmed by the Banerjee criterion. The differences and similarities in the functional properties of films are explained in terms of substrate modified magnetic phase coexistence
