Magnetic and Related Properties of Tb 4 Sb 3 Compound

An X-ray phase analysis and the metallographic examination were employed in the investigation of crystal structure of the Tb4Sb3 compound. Magnetic properties have been studied by means of magnetometric measurements, including a magnetocaloric effect, electrical resistivity and magnetoresistivity, and specific heat in broad temperature and the magnetic field ranges on a polycrystalline sample. It was confirmed that the Tb4Sb3 compound is an antiferromagnet with the temperature of the magnetic transition, T-N = 111.4 K (specific heat) or 114 K (magnetization). The results are discussed in the term of a crystal field splitting scheme.
