Magnetic refrigeration investigated as an efficient environmentally friendly and flexible alternative to conventional vapor compression systems. This magnetic technology complete with an important part of the Magnetocaloric material which must be subjected to the magnetic field generates by magnets use. A large effort invested in improving the magnetocaloric material, discoveries of outstanding materials provided new opportunities to use them as alternative working materials in active magnetic refrigeration at various temperatures. It is believed that the manganite materials with the superior magnetocaloric properties in addition to cheap materials processing cost will be the option of future magnetic [1]. This paper present an overview of different published magnetocaloric materials used in magnetic refrigeration applications over the past few years, analyze the different efficiency, the usability for these materials based on magnetic flux density used, the temperature span result and others. Thus allows us to present recommendations for improving existing magnetocaloric materials as well as discussing the features of the best magnetocaloric material for magnetic refrigeration. Lastly it remains the responsibility of decisionmakers to choose the most appropriate ones.
