Abnormal magnetic properties and high-temperature superconductivity of metal and semiconductor single crystals

摘要

The influence of the deformation on the magnetic susceptibility of molybdenum and zinc single crystals in the range 77 $DIV 300K at the magnetic fields 0,03 $DIV 2.5KOe has been investigated. It is deduced that the increase of a deformation degree causes the essential growth of paramagnetism and the occurrence of nonlinear susceptibility dependence on the intensity of a magnetic field. At room temperature and H $LS 100Oe the abnormal diamagnetism increase have been observed. This phenomenon can be explained by the occurrence of superconductive phases in the bulk of the crystal. We have established that the ten-fold abnormal diamagnetism increase is observed for (InSb)$- 0.95$/(CdTe)$-0.05$/ solid solution when the temperature falls. This phenomenon can be explained due to the emergence of metal superconductive modifications in the bulk of the crystal.
