The heat capacity and phase transition in CoFe2Se4 crystals
- 1. ANAS, Institute of Physics, Baku (Azerbaijan)
Description
The heat capacity of CoFe2Se4 crystals in interval 55-300 K is investigated. The temperature dependence reveals the anomaly showing on the presence of ferromagnetic phase transition in interval 108-135 K. The anomaly maximum value is at T=128 K temperature. The values of energy and entropy of phase transition, the coefficients of thermodynamic potential are obtained. The small value testifies to the effect that this transition is to transitions of displacement type. The behavior of anomalous heat capacity is satisfactory described by Landau's theory of phase transitions
