In order to study the phase transitions of ferroelectric NaNO2 near the Curie temperature TC and the Neel temperature TN, the linear thermal expansions xi(i=a, b, c) and the dielectric constant ϵb of the single crystals were simultaneously measured.

Successive structural phase transitions with ferroelectricity were found in TlCoCl 3 through dielectric constant measurements and D – E hysteresis loop observations. The sequence of the transitions is identical with that in RbMnBr 3 and TlFeCl 3 ,

It is found that KNiCl3, RbFeBr3, RbMnBr3, RbCoBr3 and TlFeCl3 belonging to a KNiCl3-type antiferromagnet undergo novel class of structural phase transitions which comprise magnetic phase transitions accompanied by spin-frustration in the c-plane and

The process of nucleation and growth of the incommensurate phase in the C-to-IC transition has been studied. In the course of the transition, a sample is quenched to room temperature. During quenching, the nucleated IC regions are converted to ferroe
