Chida cha LADP-4 Microwave Ferromagnetic Resonance

Zoyesera

1. Kumvetsetsa ndikudziwa bwino ntchito ndi njira zoyendetsera chipangizo chilichonse cha microwave.

2. Kumvetsetsa muyesokukonzansomfundo ndi mikhalidwe yoyesera ya ferromagnetic resonance, ndikumvetsetsa makhalidwe onse a ferromagnetic resonance mwa kuwona phenomenonmphamvu ya ferromagnetic resonance.

3. Zizindikiro za Ferromagnetic resonance za YIG polycrystallinemipira ndiKuyang'aniridwa ndi oscilloscope kuti mudziwe mphamvu ya maginito, ndi chiŵerengero cha g factor ndi gyromagnetic cha zitsanzo za polycrystallinendikuwerengedwa malinga ndi kuchuluka kwa ma microwave.

4.Thegalvanometer ya digitoimagwiritsidwa ntchito poyeza tubale pakati pa mphamvu yotulutsa ya resonant cavity ndi mphamvu ya maginito,fotokozanima resonance curve,ndi kudziwamphamvu ya maginito ya resonance. M'lifupi mwa mzere wa resonanceimatsimikiziridwa malinga ndi muyeso wa muyeso, ndi nthawi yopumulaya chitsanzo cha polycrystalline cha YIG ikuyerekezeredwa.

5. Chizindikiro cha ferromagnetic resonance cha mpira umodzi wa YIG kristaloisKuwona ndi oscilloscope, ndi chizindikiro chimodzi cha resonanceis zomwe zimawonedwa ndi gawo losinthira, kuti aphunzire njira yodziwira mphamvu ya maginito yozungulira pogwiritsa ntchito oscilloscope.

6. Phunzirani momwe mungayezerere kutalika kwa mafunde ndi kuchuluka kwa resonant cavityndi njira yofupikitsapisitoni.

7. Theubale pakati pa malingaliromphamvu yamaginito yowunikira ya chitsanzo chimodzi cha YIGndi imayesedwandikukula kwamphamvu ya maginito yolumikizana ya axis yosavuta ya maginito ndizolimbamzere wa magnetization watsimikizika. Tanisotropy constant ndi factor zimawerengedwa.
