Magnetic cooling that utilizes magnetocaloric effect has become a competitive technology in the field of refrigeration technique. This is an environment-friendly technology as it does not require any gaseous substances contrary to the conventional vapor-compression/expansion refrigeration technique. The performance of a magnetic refrigerator mainly depends on the magnetocaloric property of the substance. For the potential application of this technology, low-cost and highly efficient magnetocaloric materials are in great need as magnetic refrigerants. Therefore, it has become necessary to find...
