[en] An experimental equipment is described built within the SPIN project for research using oriented radioactive nuclei within a wide range of atom and mass numbers with half-lives of more than one hour. Nuclear orientation is based on hyperfine interaction at very low temperatures using internal magnetic fields of ferromagnetic matrices polarized with an external magnetic field. The results are given obtained on the SPIN equipment in studies: a) of hyperfine interactions of admixed atoms in different metal matrices, especially of even-even Tb isotopes in a Gd matrix; b) of nuclear magnetic resonance in oriented nuclei; c) of beta decay in oriented nuclei from the transition area around A=150, especially in Tb isotopes and in Gd and Eu isotopes.
