| Popis: | The dependence of the microhardness of KDP crystals with embedded TiO2 nanoparticles on the time passed after their exposure to a dc magnetic field has been analyzed. Samples cut from different growth sectors are found to be differently affected by magnetic treatment. In the absence of TiO2 impurity, the microhardness of the samples from the {100} growth sector decreases after the magnetic exposure, whereas the microhardness of the samples cut from the {101} growth sector changes in two stages (hardening after softening). With an increase in the TiO2 concentration, the softening stage gradually disappears in the crystals from both growth sectors. In the KDP:TiO2 crystals from the {100} sector, hardening (which was absent previously) occurs instead of softening. In the crystals from the {101} sector, the hardening arises after a shorter time. |
