LADP-4 Microwave Ferromagnetic Resonance Apparatus

Zoyesera

1. Kumvetsetsa ndikuwongolera ntchito ndi njira zoyendetsera chipangizo chilichonse cha microwave.

2. Kumvetsetsa njirarementmfundo ndi zoyeserera za ferromagnetic resonance, ndikumvetsetsa mawonekedwe a ferromagnetic resonance powona pheno.manondi ferromagnetic resonance.

3. Zizindikiro za Ferromagnetic resonance za YIG polycrystallinemipira ndikuyang'aniridwa ndi oscilloscope kudziwa resonance magnetic field, ndi g factor ndi gyromagnetic chiŵerengero cha zitsanzo polycrystallinendikuwerengedwa molingana ndi ma frequency a microwave.

4.Thedigito galvanometeramagwiritsidwa ntchito kuyeza tkugwirizana pakati pa resonant cavity linanena bungwe mphamvu ndi maginito,fotokozaniresonance curve,ndi kuzindikiraresonance magnetic field. Mzere wa resonance m'lifupizimatsimikiziridwa molingana ndi kupindika kwake, komanso nthawi yopumulazitsanzo za YIG polycrystalline zikuyerekezedwa.

5. Chizindikiro cha ferromagnetic resonance cha YIG single crystal mpiraiskuwonedwa ndi oscilloscope, ndi chizindikiro chimodzi cha resonanceis kuwonedwa ndi gawo shifter, kuti aphunzire njira yodziwira maginito a resonant ndi oscilloscope observation.

6. Phunzirani momwe mungayezere kutalika kwa mawonekedwe a waveguide ndi ma frequency a resonantnt chikwamapa short-circuitpisitoni.

7. Themgwirizano pakati pa orientedresonance magnetic field ya YIG single crystal samplendi amapimidwa, ndikukula kwaresonance magnetic field of easy magnetization axis ndizolimbamagnetization axis yatsimikiziridwa. Tiye anisotropy nthawi zonse ndi factor amawerengedwa.
