PHOTO-INDUCED EFFECT ON THE PERMEABILITY OF YIG SINGLE CRYSTALS WITH Pb IMPURITY
نویسندگان
چکیده
The influence of irradiation with white light on the permeability at 77 K is investigated on p-type yttrium iron garnet single crystals with Pb impurity. Theexistence of an irreversible photo-magnetic effect and photo-accelerated disaccommodation is demonstrated in p-type YIG. These effects are explained by a modified two center model in which Fe4+ plays an important role.

Effect of impurities on the optical properties of KTP single crystals grown from flux
In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...
متن کاملExperimental Study on the Magnetomechanical Characteristics of Ni-Mn-Ga Ferromagnetic Shape Memory Alloy Single Crystals
Magnetic shape memory properties of Ni-Mn-Ga single crystals were characterized by measurement of stress-induced martensite reorientation under constant magnetic fields. Also magnetic field-induced strain as a function of the applied magnetic field under different constant compressive stress levels has been investigated. All the experiments were performed at room temperature in which the sample...
