摘要：
Fe1.087Te exhibits three phases in the pressure range from ambient to 16.6 GPa and becomes amorphous at higher pressures. All three phases have tetragonal symmetry. The low pressure T-phase is stable in the pressure range 0 <= P < 4.1 GPa and is found to be relatively soft having zero pressure bulk modulus B-0 = 36(1) GPa. The intermediate cT-phase is less compressible with B-0 = 88(5) GPa and stable in the pressure range 4.1 <= P < 10 GPa while a more compressible phase was observed between 10 and 16.6 GPa.
