Abstract:
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.
