Physical properties of TlFe^sub 3^Te^sub 3^ near its first order transition

Pseudo-one-dimensional Chevrel compound TlFe3Te3 undergoes a first-order phase transition from paramagnetic to ferromagnetic at Tc = 220 K. Here we report a systematic study of magnetization, heat capacity and resistivity on polycrystalline TlFe3Te3 near Tc. The enhancements of Tc in an external mag...

Summary:Pseudo-one-dimensional Chevrel compound TlFe3Te3 undergoes a first-order phase transition from paramagnetic to ferromagnetic at Tc = 220 K. Here we report a systematic study of magnetization, heat capacity and resistivity on polycrystalline TlFe3Te3 near Tc. The enhancements of Tc in an external magnetic field and a hydrostatic pressure follow the Clausius-Clapeyron relations. The large enhancement of the Tc under the pressure indicates that the unit cell shrinks from para- to ferro-magnetic phase.
