    Abstract: Using Raman scattering and optical birefringence we have investigated a low-temperature phase transition in single crystal of the two-dimensional Na5RbCu4(AsO4)4Cl2. Phonon anomalies point to a first order nature of the transition. The observed transition is most probably related to a order-disorder transition of the Rb ion positions along the z axis within the ionic framework of mixed alkali metal chloride lattices.

    Abstract: The magnetic intermediate state (MIS) formed in a vicinity of a magnetic field induced first order phase transition was investigated by using visual and magnetooptical methods in the antiferromagnetic TbFe3(BO3)4. The area of existence of MIS in the interval of temperatures from 6 to 15 K in H-T plane was defined. It was calculated the energy of domain wall between an antiferromagnetic and high field magnetic phase.
