By making use of the result obtained in Part I, the numerical calculation of A in ω=A・M_d(T) of Fe^57 in ferromagnetic iron has been carried out and the calculated value of A is found to become 1.4_7〜1.9_4×10^5gauss^<-l>sec<-1>, corresponding to the assumed values, ranging 2 to 1 of η.i.e., the amount in percentage of the admixture effect which is generally expected to be a few percent or less. The comparison with the observed value, i.e., A=1.67×l0^5gauss<-1>sec<-1> at T=0 for Fe^57 in ferromagnetic iron seems to be quite satisfactory. It shoud be remarked that the more or less spreaded, atomic orbitals of 3d-electron within the crystal compared with the Hartree-data of an isolated Fe atom may give favourable results for the nuclear magnetic resonance frequency of Fe crystal. The hyperfine field felt by Fe^57 nucleus within the ferromagnetic Fe has also been calculated to become H _hy=-3.0〜-3.9x10^5 0e at T=0, which agree remarkably well with the observed values of -3.39×10^5 Oe by the nuclear magnetic resonance method and of -3.33×l0^5 0e by the Mossbauer-type experiment.
