FIG. 1.

(Color online) Temperature dependence of field-cooled magnetization for Sm1-x Sr x MnO3 (x = 0.42, x = 0.44, and x = 0.46) taken at a field of 10 mT. Inset: Temperature dependence of inverse susceptibility for x = 0.42. The dashed line denotes high-temperature fitting to the Curie-Weiss law.

FIG. 2.

(Color online) Field-dependent magnetization (M-H) curves measured around TC for Sm1-x Sr x MnO3 with (a) x = 0.42 and (b) x = 0.46. The corresponding Arrott plots are displayed in panels (c) x = 0.42 and (d) x = 0.46.

Image of FIG. 3.
FIG. 3.

(Color online) (a) Temperature dependence of (−ΔS M ) of SSMO with x = 0.44 for field changes of 0.1–5.0 T. Inset: Entropy change peaks for each composition for μ0ΔH = 5 T. (b) Field-dependent RC values for each composition before (dashed lines) and after (solid lines) subtracting hysteretic losses. Inset: Virgin and return M-H curves at TC.
