An attempt is made to investigate the electric susceptibility mass of electrons in A₃^IIB₂^V materials under arbitrary magnetic quantization by including the influence of spin and broadening of Landau levels, respectively. It is found, taking n-Cd₃P₂ as an example, that the same mass oscillates with inverse quantizing magnetic field and also with the angle of orientation of the same field. Besides, the same mass increases with increasing carrier degeneracy and the crystal field splitting parameter enhances the numerical magnitudes in all the three variations. The corresponding results for the three-band Kane model, the two-band Kane model and that of parabolic energy bands have also been obtained as special cases of our generalized derivation.
