Abstract:

Modern technology for refrigerators and coolers is
based on the chemical gas Chlorofluorocarbon (CFC) compression method that is
indicative of a high consumption of electricity. The CFC is also understood as
a reason for global warming. One of the solutions to this issue is magnetic
refrigeration technology, which is environmentally friendly because it does not
use any hazardous chemicals or ozone depleting/greenhouse gases. Magnetic
refrigeration technology is based on the magnetocaloric effect of magnetic
refrigerant materials. Exploring the magnetocaloric effect of magnetic
refrigerant materials is important because these contain many of the physical properties
needed for magnetic refrigeration technology. Herein, the present work reports
on the magnetocaloric effect of La0.7Ca0.3Mn1−xSnxO3
(x = 0.0, x = 0.02 and x = 0.04)
compound samples produced with the solid state reaction technique. Curie
temperature TC obtained
for the La0.7Ca0.3Mn1−xSnxO3
(x = 0.0, x = 0.02 and x = 0.04)
are 260 K, 176 K and 170 K with -ΔSM max of
4.32 J×kg-1×K-1,
1.61 J×kg-1×K-1
and 1.24 J×kg-1×K-1
and a refrigerant capacity of 48 J/kg, 41.43 J/kg and 28.53 J/kg for x = 0.0, x
= 0.02 and x = 0.04, respectively. A
small addition of Sn-doped resulted in a significant decrease of more than
80 K on the Curie temperature scale compared to that
of La0.7Ca0.3MnO3.
The large gap in the decreasing magnetic temperature phase transition might be
useful as an option of metal/transition metal doped for tuning the Curie
temperature of magnetic refrigerant materials.
