Abstract

Magnetic properties and magnetocaloric effects of Tb₆Co _1.67Si₃ have been investigated by magnetization measurement. This compound is of a hexagonal Ce₆Ni₂Si ₃-type structure with a saturation magnetization of 187 emu/g at 5K and a reversible second-order magnetic transition at Curie temperature T _C = 186K. A magnetic entropy change ΔS = 7Jkg ^-1K^-1 is observed for a magnetic field change from 0 to 5T. A large value of refrigerant capacity (RC) is found to be 330J/kg for fields ranging from 0 to 5T. The large RC, the reversible magnetization around T _C and the easy fabrication make the Tb₆Co _1.67Si₃ compound a suitable candidate for magnetic refrigerants in a corresponding temperature range.
