    • Abstract


      Investigation of dielectric properties of layered compound, TlGaSe2, showed that it is a ferroelectric (𝑇c = 105.5 K) with an intermediate incommensurate phase (𝑇i = 114.5 K). Our magnetic studies of layered compounds, TlCrS2 and TlCrSe2, for the first time revealed that the magnetic phase transition in these compounds are quasi two-dimensional ferromagnetic in nature and magnetic characteristics are 𝑇c = 90 K, $T^{p}_{C}$ = 115 K, 𝜇eff = 3.26 𝜇B and 𝑇c = 105 K, $T^{p}_{C}$ = 120 K, 𝜇eff = 3.05 𝜇B, respectively. Using the method of DTA, areas of homogeneous and heterogeneous coexistence of ferroelectric and ferromagnetic phase transitions in the systems, TlGaSe2–TlCrS2 and TlGaSe2–TlCrSe2, were identified. The low-dimensional solid solutions and eutectic alloys in these systems can be used as basic materials for plenty of functional recorders.
