The properties of layered transition metal dichalcogenides intercalated with 3d metal ions are investigated. The influence of the gradient magnetic field at the intercalation front on the properties of intercalants is studied. It is shown that Co0.1Sb2Te3, Ni0.1Bi2Te3 and Ni0.2In4Se3 intercalates have ferromagnetic properties at room temperature. The dependences of the magnetic moment on the magnetic field strength along and across the layers of Co0.1Sb2Te3, Ni0.1Bi2Te3 and Ni0.2In4Se3 intercalates have the hysteresis loop. The obtained values of the coercive force of the studied samples are typical for hard ferromagnets. The properties of the obtained intercalates are determined by the crystal structure of layered crystals, localization and magnetic interaction of intercalant atoms between the layers of the crystal matrix and the influence of the magnetic field on the processes of exchange interaction between them.
