| Abstract: | Magnetic properties and magnetocaloric effects of
Tb6Co1.67Si3 have been investigated by magnetization
measurement. This compound is of a hexagonal
Ce$_{6}$Ni$_{2}$Si$_{3}$-type structure with a saturation
magnetization of 187\,emu/g at 5\,K and a reversible second-order
magnetic transition at Curie temperature $T_{\rm C} = 186$\,K. A
magnetic entropy change $\Delta S =
7$\,J\,$\cdot$\,kg$^{-1}$\,$\cdot$\,K$^{-1}$ is observed for a
magnetic field change from 0 to 5\,T. A large value of refrigerant
capacity (RC) is found to be 330\,J/kg for fields ranging from 0 to
5\,T. The large RC, the reversible magnetization around $T_{\rm C}$
and the easy fabrication make the Tb6Co1.67Si3
compound a suitable candidate for magnetic refrigerants in a
corresponding temperature range. |
