Description The effect of substitution of Co and Fe for Ni in TbNi(5) on the structural, magnetic and magneto-thermal properties has been investigated. Considerable enhancement of Curie temperature is observed with Fe substitution, whereas the increase is nominal in the case of Co. Neutron diffraction measurements reveal the redistribution of moments and site preference of substitutional ions in Ni 2c and 3g sites. In TbNi(4)Fe, both Ni and Fe as well as Tb are found to carry moment while in the case of TbNi(4)Co, mainly Tb carries the moment. Magnetocaloric behavior has been investigated from the magnetization and the heat capacity measurements. The magnetic and magnetocaloric properties are found to be strongly correlated in these compounds. (C) 2011 Elsevier B.V. All rights reserved.
