Recently magnetic properties of the R7Pd3 intermetallic compounds were examined . For La7Pd3 the electrical resistivity exhibits a tendency to saturation at higher temperatures and the superconducting transition at 6 K. Ce7Pd3 has an antiferromagnetic transition at 5 K, while Pr7Pd3 has such transition at only 1.7 K. Nd7Pd3 shows two characteristic temperature: first one 33 K related to ferromagnetic – antiferromagnetic transition and the second 38 K related to transition antiferromagnetic – paramagnetic. Sm7Pd3 exhibits two sharp peaks connected with antiferromagnetic – ferrimagnetic transition at 18.4 K and at 167 K connected with transition from ferrimagnetic state to paramagnetic. All measured properties are sensitive to the pressure. Magnetocaloric properties of Gd7Pd3 were investigated .
