Studies of magnetic and transport properties of the 1212 compounds MA'_{2}A''Cu_{2}O_{7-x} (M 3D Al or Tl; A'= Sr or Ba; A''= RE, Y, and Ca) revealed a number of interesting magnetic phenomena. Apart from high-temperature superconductivity, these compounds exhibit spontaneous antiferromagnetism, field induced antiferromagnetism or ferromagnetism. The different magnetic orders and superconductivity may be realized in the same compound as a result of the phase separation.

Magnetic and specific heat measurements have been performed on polycrystalline TbNi_2, ScNi_2 and their solid solutions Tb_{1-x}Sc_{x}Ni_2 (x = 0.1, 0.2). These compounds were synthesized using high-purity rare-earth metals. It has been found that the magnetic susceptibility of the nonmagnetic ScNi_2 compound exhibits a very weak temperature dependence characteristic of the Pauli paramagnets. TbNi_2, Tb_{0.9}Sc_{0.1}Ni_2 and Tb_{0.8}Sc_{0.2}Ni_2 are typical Curie-Weiss paramagnets and are ferromagnetically ordered below 36 K. As revealed by room-temperature X-ray powder diffraction all the Tb_{1-x}Sc_{x}Ni_2 solid solutions have the cubic Laves C15-type superstructure. The Debye temperature, phonon and conduction electron contributions as well as the magnetic part of heat capacity were determined. The magnetocaloric effect has been studied by means of specific heat measurements in magnetic fields of 0.42 and 1 T. The effect of rare-earth substitution in ScNi_2 on the magnetic and magnetocaloric properties will be discussed.
