Influence of Preliminary Thermomagnetic Treatment on the Yield Point of NaCl:Ni Crystals

The influence of preliminary annealing (3 h, 1000 K), subsequent quenching in liquid nitrogen, and short magnetization in a constant magnetic field (0.5 h, 0.48 T) prior to deformation on the yield point of NaCl : Ni crystals is discovered. The effect depends on the time of sample storage between quenching and magnetization and is maximal 40 h after quenching. © 2003 MAIK "Nauka/Interperiodica".
