The magnetocaloric properties of cobalt ferrite
nanoparticles were investigated to evaluate the potential of
these materials as magnetic refrigerants. Nanosized cobalt
ferrites were synthesized by the method of sol–gel combustion.
The nanoparticles were found to be spherical with
an average crystallite size of 14 nm. The magnetic entropy
change ( Sm) calculated indirectly from magnetization
isotherms in the temperature region 170–320 K was
found to be negative, signifying an inverse magnetocaloric
effect in the nanoparticles. The magnitudes of the Sm values
were found to be larger when compared to the reported
values in the literature for the corresponding ferrite materials
in the nanoregime. |
