Photomagnetic effects

Direct influence of electromagnetic radiation on magnetic properties has been detected at low temperatures (T < 150°K) in Si-doped YIG (Y 3 Fe 5-x Si x O 12 ) and in Ga-doped CdCr 2 Se 4 (Cd 1-y Ga y Cr 2 Se 4 . Its manifestations are 1) a change in crystalline anisotropy observed in ferromagneti...

Zusammenfassung:Direct influence of electromagnetic radiation on magnetic properties has been detected at low temperatures (T < 150°K) in Si-doped YIG (Y 3 Fe 5-x Si x O 12 ) and in Ga-doped CdCr 2 Se 4 (Cd 1-y Ga y Cr 2 Se 4 . Its manifestations are 1) a change in crystalline anisotropy observed in ferromagnetic resonance and torque measurements at high dopes ( 0.1 < x < 0.3 ) and 2) a reduction in initial permeability and an increase in coercive forceoccurring for low dopes ( x < 0.05, y = 0.015 ). These changes are produced by irradiation with light of wavelength
