A phenomenological theory was developed that described the effect of a magnetic field on the defect reactions in a solid. The theory was based upon a concept regarding the lattice magnetism according to which a defect induces a magneto-active (magnon) branch in the spectrum of elementary excitations of a crystal lacking a magnetic structure in the absence of defects. The probability of a defect complex disintegrating in a magnetic field was calculated in terms of the magnon mechanism of the reaction.
