Ferromagnetism of structure-disordered surface layers of molybdenum and zinc single crystals

The influence of the plastic deformation on the magnetic susceptibility of molybdenum and zinc has been studied. It is found that a sharp increase of the paramagnetic susceptibility after the compression deformation essentially depends on the state of the crystal surface before deformation. The chemical removal of the surface layer leads to disappearing of the observed effect. A concept of connection of arising unusual magnetic behavior of molybdenum and zinc with appearance of microcracks in the surface layer under deformation is proposed. Microcracks are supposed to lead to anomalously high magnitudes of the magnetic susceptibility.
