• The effects on phonon instability due to the spin and anisotropy of effective masses of electrons and holes which follow ellipsoidal-parabolic energy-momentum relations are studied. The anisotropic and spin effects of these charge carriers would exhibit themselves as particularly shaped forms of the phonon changing rate against the alternate bands of the magnetic field so that the feature may be used as a new method of determining relevant spin and orbital effective masses with possibly very high precision. Holes although contributing constructively to the current of electrons are found tending to annihilate the phonons which electrons tend to create. Brief discussions are also given to the situations of observing phonon instability in semimetals and semi-conductors.
