Abstract [en]

The linear dispersion relation for compressional magnetoacoustic waves in a quantum magnetoplasma, is derived, taking into account the quantum Bohm potential and the rnagnetization of electrons due to the electron-1/2 spin effect. It is found that the quantum forces produce the wave dispersion at quantum scales, which depend on the external magnetic field strength.
