%X We present a study of magnetocaloric effect in the colossal magnetoresistance material (La0.6Dy0.1)Sr0.3MnO3. From the measurement and calculation of magnetization under various temperatures, we have discovered large magnetocaloric effect with the ferromagnetic-paramagnetic transition, additional magnetism exchange action introduces additional magnetic entropy change. This result suggests that (La0.6Dy0.01)Sr0.3MnO3 is a suitable candidate as working substances at room temperature in magnetic refrigeration technology.
