The equation of state and the shear modulus data of sintered Nd₂Fe₁₄B were investigated up to 140 GPa by the Gruneisen’s model, the volume superposition principle and the Hugoniot’s relations. Then, the results were compared to the prior experiments with a standard deviation of 0.125% from 18 GPa to 78 GP; and then, the loading pressure was extended to higher. Meanwhile, the softening feature has not been observed both in adiabat and shear modulus throughout the interested range.
