Magnetoplastic effects in solids

A model for non-thermal action of microwave radiation on oxide film/semiconductor structures

“…The most likely reason for appearance of nonthermal effect of microwave radiation is presence in a crystal of nonequilibrium states that cause sensitivity of defect structure to action of microwave radiation. In particular, it was noted in [17,18] when considering effect of low electric fields on nonmagnetic crystals that such effect is just due to presence of structural defects in them. It may be assumed that microwave field (as magnetic field) can lower the potential barriers (related to random distribution of the fields of intrinsic stresses in a crystal) that must be surmounted to provide dislocation movement [17,18].…”

“…The obstacles may be several impurity atoms and cation vacancies as well as be of variable composition [17,18]. Relaxation of intrinsic stresses leads to inverse effect, namely, gradual decrease of the number of moving dislocations.…”

Effect of weak magnetic fields treatment on photoluminescence of III-V single crystals

“…This method of physical action is of interest and promising from scientific point of view as well as important practically [1][2][3][4]. The energy absorbed as a result of treatment in such magnetic fields is three orders of magnitude smaller than the thermal energy of electrons at room temperature, which complicates the explanation of the observed effects.…”

“…The interaction of WMF with indium phosphide was studied earlier [13], but in that case both the material microstructure and regime of treatment were different. WMF induced modification studied in [1,14,15] was related to the change of the positions of dislocations in solid state. In those works, a possibility in principle for dislocation motion under WMF action was demonstrated.…”

“…The energy absorbed as a result of treatment in such magnetic fields is three orders of magnitude smaller than the thermal energy of electrons at room temperature, which complicates the explanation of the observed effects. However, even this energy action can cause both reversible and irreversible changes in the defect subsystems of solids [1]. Despite numerous investigations in this field and some proposed explanations, the problem of WMF interaction with practically important III-V semiconductors still remains open [3].…”
