Abstract
In this work intercalated compounds in the Cr-MoSe2 system were synthesized for the first time. Their magnetic properties are studied at various intercalant concentrations, temperatures and magnetic fields. The temperature dependences of effective magnetic moments and positive paramagnetic Curie temperatures in the paramagnetic region evidence the feasible ferromagnetic interactions between intercalated atoms. The existence of low-temperature ferromagnetic state in CrxMoSe2 is confirmed by hysteresis phenomena in temperature dependences magnetic susceptibility and field dependences of magnetization. The change in the magnetic state affects the character of the temperature dependences of the resistivity.

Summary
The temperature dependences of effective magnetic moments and positive paramagnetic Curie temperatures in the paramagnetic region evidence the feasible ferromagnetic interactions between intercalated atoms. The intercalation of 3d-metal (M) atoms having a magnetic moment into TX2 leads to the formation of compounds with different magnetic behaviors from paramagnetic and spin-glass type to magnetically ordered states. The properties of intercalated transition metal dichalcogenides MxTX2 are found to depend both on the type of inserted M atoms and on the type of the starting compound.
