The notion of the degenerate critical point (DCP) of phase transitions is introduced. The theory of antiferromagnet properties near such points is developed. Various instances are given of realization of the Morin point as a DCP and its modifications resulting from symmetry breaking due to inclusion of new internal and external interactions. Phase diagrams show lines of zero‐order phase transition critical points.
