Assuming the second Grüneisen parameter q has the form of q ( T, P ) = q ( T , 0) ( V ( T, P )/ V ( T , 0)) n , the three calculated formulas of Grüneisen parameter; Debye temperature and thermal expansivity of ε‐Fe are presented. The calculated results show that the agreement with the experimental data is good. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
