An attempt is made to investigate the effects of varying the orientation of a quantizing magnetic field on the effective mass in tetragonal semiconductors. It is found, taking n‐Cd 3 As 2 as an example, that the crystal‐field splitting results in different effective masses at the Fermi level corresponding to different magnetic sub‐bands. These effective masses are found to be significantly influenced by the orientation of the magnetic field with respect to the c ‐axis. This behaviour is further noted to be strongly dependent on the carrier concentration but is relatively much less sensitive to changes in the magnetic field strength.
