Isithombe Esivelele Se-LADP-4 Microwave Ferromagnetic Resonance Apparatus

I-LADP-4 Microwave Ferromagnetic Resonance Apparatus

Incazelo emfushane:

I-Ferromagnetic resonance idlala indima ebalulekile kumagnetism ngisho naku-solid state physics. Iyisisekelo se-microwave ferrite physics. I-Microwave ferrite isetshenziswe maqondana nobuchwepheshe be-radar kanye nokuxhumana kwe-microwave. Ezikhathini zanamuhla, i-ferromagnetic resonance, njenge-electron spin resonance kanye ne-magnetic resonance imaging, iyindlela ephumelelayo yokufunda izakhiwo ezinkulu kanye nesakhiwo se-microscopic sezinto.
I-microwave ferromagnetic resonance apparatus yakhiwe kakhulu izingxenye ezintathu: uhlelo lomshini oluyinhloko lokuhlola, uhlelo lwe-microwave kanye nohlelo lwe-magnet. Ngaphezu kwalokho, i-dual trace oscilloscope (ingxenye ongayikhetha) kufanele ifakwe kulolu vivinyo.

Ukuhlolwa

1. Qonda futhi uqonde imisebenzi nezindlela zokulawula zedivayisi ngayinye ye-microwave.

2. Qonda isilinganisoukulungiswaizimo eziyisisekelo kanye nezivivinyo ze-ferromagnetic resonance, futhi uqonde izici ezijwayelekile ze-ferromagnetic resonance ngokubuka i-phenoi-menonukuzwakala kwe-ferromagnetic.

3. Izimpawu ze-Ferromagnetic resonance ze-YIG polycrystallineamabhola kukhonaokubonwe yi-oscilloscope ukuze kutholakale insimu yamagnetic ye-resonance, kanye nesilinganiso se-g factor kanye ne-gyromagnetic samasampula e-polycrystallinekukhonakubalwa ngokwemvamisa ye-microwave.

4.Ii-galvanometer yedijithaliisetshenziselwa ukukala u-tubudlelwano phakathi kwamandla okukhipha umgodi we-resonant kanye nensimu yamagnetic,chazaijika le-resonance,futhi unqumeinsimu yamagnetic ye-resonanceUbubanzi bomugqa we-resonancekunqunywa ngokuya ngejika lokulinganisa, kanye nesikhathi sokuphumulaKulinganiselwa ukuthi isampula ye-YIG polycrystalline ilinganisiwe.

5. Isignali ye-ferromagnetic resonance yebhola elilodwa lekristalu le-YIGiskubonwe yi-oscilloscope, kanye nesignali eyodwa ye-resonanceis kubhekwe yi-phase shifter, ukuze kufundwe indlela yokunquma insimu yamagnetic ephendulayo ngokubuka kwe-oscilloscope.

6. Funda ukuthi ungalinganisa kanjani ubude be-waveguide kanye nemvamisa ye-resonant ye-resonaumgodi we-ntnge-short-circuitiphistoni.

7. Iubudlelwano phakathi kokuqondiswainsimu yamagnetic ye-resonance yesampula yekristalu eyodwa ye-YIGfuthi kulinganiswa, kanyeusayizi weinsimu yamagnetic ye-resonance ye-axis elula ye-magnetization kanyekanzimai-axis ye-magnetization inqunywa. Ti-anisotropy constant kanye ne-factor kubalwa.
