V. Kapustianik et al., PHASE-TRANSITIONS IN [N(C2H5)(4)](2)MECL2BR2 (ME=ZN, CO, CU) SOLID-SOLUTIONS, Physica status solidi. a, Applied research, 161(2), 1997, pp. 515-521
In this paper dielectric permittivity and birefringence of [N(C2H5)(4)
](2)MeCl2Br2 (Me = Zn, Co, Cu) have been investigated. As the results
of our measurements we present structural phase transitions in these f
erroelectric crystals.
