Abstract

The phase transition from the paramagnetic to the ferromagnetic phase in a van der Waals volume Fe3GeTe2 compound was studied. A renormalization group approach was used, the action for which was constructed using group theoretical analysis to determine the irreducible representation of the spatial group responsible for this transition, in the case of magnetic moments localized on iron. It is shown that such a representation exists, which allows the orientation of magnetic moments along the c axis of the crystal. The influence of vacancies in one of the iron positions on this transition was considered using replica method by analogy with the description of frozen impurities. Power law of change magnetization was found near the transition taking into account the presence of vacancies. A condition has been determined when vacancies are pressure this transition. Possible influence of strong electron correlations and free electrons on the stability of the ferromagnetic phase was analyzed using the t–J model for non-degenerate electrons. In the generalized random phase approximation, the additional contribution of free electrons to the formation of long-range ferromagnetic order occurs through Pauli susceptibility gas of free electrons. The condition for the stability of the ferromagnetic state in this case was written out.
