摘要: Abstract The dielectric properties of TlSbSe 2 have been studied at microwaves in a wide temperature region. It is shown that the crystal possesses high and anisotropic permittivity caused by phonons contribution. dependence polar direction according to Curie-Weiss law with negative Curie shows virtual ferroelectric. Between 4.2 700 K has sequence structural phase transitions, including transition supposed incommensurate superionic phase. cause anomalies electric conductivity crystal.
