Impact of compound Pr doping on the magnetic and magnetocaloric properties of Sr2-xPrxFeMoO6 Double perovskite

摘要

The present invention provides a double Perovskite compound represented by Sr_(2-x)Pr_xFeMoO_6. The double Perovskite compound of Sr_(2-x)Pr_xFeMoO_6 according to the present invention not only has a high curie temperature by adding praseodymium (Pr) to a Sr_2FeMoO_6 compound, thereby replacing a portion of strontium (Sr) with Pr, but also can be usefully used as a magnetic coolant of a magnetic refrigerating apparatus such as an environmentally friendly refrigerator, an air conditioner or the like using a room temperature magnetic refrigeration technology by improving magnetic and cooling properties.
