Magnetic and electrical transport properties of RE9Ni24Sn49 compounds (RE=Y, Ce, Pr, Sm and Tb)

Abstract Magnetic and electrical transport properties of cubic phases RE 9 Ni 24 Sn 49 (RE=Y, Ce, Pr, Sm and Tb) have been investigated by means of magnetic susceptibility, magnetisation, electrical resistivity and Seebeck effect measurements. The Ce-, Pr- and Tb-based compounds order antiferromagnetically at T N =3.1, 4.5 and 4.2 K, respectively, Sm 9 Ni 24 Sn 49 remains paramagnetic down to the lowest temperature studied, while Y 9 Ni 24 Sn 49 is a weak Pauli paramagnet. All the materials studied exhibit metallic character of their electrical conductivity and thermoelectric power.
