Figure 6: Changes of microwave transmittance and MD structure by the H-MWNF structure.
From: Adaptive microwave impedance memory effect in a ferromagnetic insulator
(a,b) Transmitted probing microwave power for forward (a) and backward (b) fm-sweeps, where p0 is the transmitted power measured after initial fm-sweeps, and powers of modulation and probing microwave were 20 and −10 dBm, respectively. The transmitted power was averaged for four modulation sweeps after the initial sweep. Arrows indicate periodic changes of transmitted power. (c) Line profile at fp=1.3 GHz. The error bars represent the s.d. of the averaged data. (d) Averaged changes of magnetic domain structure (gray) as a function of fm, and the H-MWNF distribution images (colour). (e) Hysteresis of MD modulation at 1.0 and 1.5 GHz, where the hysteresis is a difference of MD images measured in forward and backward sweeps. (f) MD modulation processes from 1.3 to 1.6 GHz, where arrows indicate the modulation sweep direction.
