In the present paper, the authors report analytically on the nonlinear instability and the modifications in the spectra of acoustic wave modes in magnetized semiconductor quantum plasma. The modification resulted from the emergence of new spin-dependent acoustic wave modes that can be controlled and manipulated through external magnetic fields. We consider that the origin of the nonlinearity lies in the nonlinear induced current density in an n-type InSb semiconductor irradiated by CO2 laser at 77 K. The QMHD (Quantum MagnetoHydrodynamic) model is extended for spin effect to investigate the dynamics of acoustic waves and a novel way to utilize the spin properties of electrons in semiconductor devices for various applications.
