Brodovoi A. Magnetic properties of lattice-disordered submagnetic solids

It has been established that, sharp increase of paramagnetism and nonlinear dependence of susceptibility of magnetic field appeared as a result of a compressive deformation in the molybdenum, zinc and silicium monocrystals. This effect has been called as magnetic-deformation effect (MDE). The concept of correlation of unusual magnetic properties of deformed materials with occurrence of micro-discontinuities with typical sizes ~10 А has been proposed. It has been shown that, the magnetic-deformation effect on crystals with different physical properties such as molybdenum, zinc, silicium and semi-conducting solid solutions is caused by the same reason - failure of crystal structure. The influence of exposure on magnetic and electric fields on microhardness and spectral distribution of photoconductivity of deformed zinc, silicium and gallium arsenide crystals has been investigated. It has been shown that, continuous exposure of such samples on the magnetic and electric fields resulted in redistribution and disappearance of the flaws in deformed samples. This disappearance of flaws is reflected in recovery of magnetic and mechanical properties. The established effect will be helpful for development of new methods for modification of physical properties of materials and for production of materials with improved physical properties.
