Strongly Frequency-dependent Photoinduced Magnetic Disaccommodation in YIG: 0.001 Ca
Strongly Frequency-dependent Photoinduced Magnetic Disaccommodation in YIG:0.001 Ca

By measuring frequency dependence of photoinduced double peaks of disaccommodation, DA as a function of temperature was observed at very low frequency: 0.07 similar to 0.30 kHz, in a single crystal of yttrium iron garnet. YIG with small amounts of Ca: 0.001, while only single peak existed at the higher frequency 0.5 kHz. The behavior is explained based on theoretical approach on a domain wall dynamics.
