Magnetic properties of Dy${}_{100-x}$In${}_x$ ($x = 0,1,2,3$) solid solutions for low temperature magnetic refrigeration technique

A promising form of the natural gas use is the liquefied gas, which has a number of advantages. Due to its properties, it is easier to transport, explosion-proof, non-toxic, does not corrode metal, and today it is the most environmentally friendly fuel. Among the various alternative technologies that could be used in refrigeration devices for producing the liquefied natural gas, the magnetic refrigeration technology is attracting the attention of researchers around the world. Dozens of prototypes of cooling devices based on various families of magnetic materials have been created in the world; however, their mass use is still far away and the process of searching for materials is actively continuing. Our research is aimed at studying the physical properties of the solid solutions Dy$_{100-x}$In$_x$ ($x = 0, 1, 2, 3$), promising for use in the technology of the liquefaction of natural gases.
