•Tb2Fe17 single-phase synthesized by simple arc-melting without any heat treatment.•The crystal structure is hexagonal with P63/mmc space group.•The magnetic entropy change of the sample was determined by Maxwell relation.•Hyperfine parameters, magnetic and magnetocaloric properties were studied.
We have synthesized the intermetallic Tb2Fe17 compound in hexagonal crystal structure by arc-melting without annealing. X-ray diffraction pattern has been refined by Rietveld method. The crystal structure is hexagonal with P63/mmc space group (Th2Ni17-type). The Mössbauer spectrum of Tb2Fe17 compound has been analyzed with seven magnetic sextets assigned to the inequivalent crystallographic sites. The temperature dependence of magnetization data revealed that Tb2Fe17 exhibits a second-order ferromagnetic to paramagnetic phase transition in the vicinity of Curie temperature (TC=412 K). The relative cooling power around the magnetic transition and the Arrott plots are also reported.
