Giant and reversible extrinsic magnetocaloric effects in La0.7Ca0.3MnO3 films due to strain
Significance of output:
Magnetocaloric effects arise in magnetic materials when changes in applied magnetic field bring about thermal changes, and could form the basis for efficient refrigeration technologies. The paper reports for the first time the creation of giant and reversible magnetocaloric effects induced through a strain-mediated feedback mechanism occurring near a structural phase transition. The main significance of the work is that it paves the way for discovering giant magnetocaloric effects in a wide range of magnetic materials, and a parallel development of artificial nanostructured materials for practical applications.
