Anomalies of the field emission process in a magnetic field
The results of an experimental study of the field emission (FE) of W, Nb, and Mo point microcrystals in a magnetic field are presented. The state of the emitter's material changes when a high-density FE current flows in a magnetic field, which leads to an expansion (or contraction) of the field-emission image, onset of oscillations and a cutoff of the FE current with time. It is assumed that under these conditions a metal-insulator phase transition, stimulated by the deformation of the microcrystal's point, may occur.
