I-LADP-4 Microwave Ferromagnetic Resonance Apparatus

Incazelo emfushane:

I-Ferromagnetic resonance idlala indima ebalulekile kumagnetism ngisho ne-solid state physics. Kuyisisekelo se-microwave ferrite physics. I-Microwave ferrite isetshenziswe ngokobuchwepheshe be-radar kanye nokuxhumana nge-microwave. Ezikhathini zanamuhla, i-ferromagnetic resonance, njenge-electron spin resonance kanye ne-magnetic resonance imaging, iyindlela ephumelelayo yokutadisha izakhiwo ze-macroscopic kanye ne-microstructure yezinto zokwakha.
I-Microwave ferromagnetic resonance apparatus yakhiwa ikakhulukazi izingxenye ezintathu: uhlelo lomshini oyinhloko wokuhlola, uhlelo lwe-microwave kanye nesistimu kazibuthe. Ngaphezu kwalokho, i-double trace oscilloscope (ingxenye ongayikhetha) izohlonyiselwa ukuhlolwa.

Izivivinyo

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

2. Qonda isilinganisorementUmgomo nezimo zokuhlola ze-ferromagnetic resonance, futhi uqonde izici ezijwayelekile ze-ferromagnetic resonance ngokubheka i-pheno.indodaukusabela kwe-ferromagnetic.

3. Amasiginali we-Ferromagnetic resonance ye-YIG polycrystallineamabhola kukhonaibonwa yi-oscilloscope ukuze kutholwe inkambu kazibuthe resonance, kanye ne-g factor kanye ne-gyromagnetic ratio yamasampuli e-polycrystallinekukhonaibalwa ngokuya ngefrikhwensi ye-microwave.

4.Ii-galvanometer yedijithaliisetshenziselwa ukukala u-tubudlelwano phakathi kwamandla okukhipha i-resonant cavity kanye nenkundla kazibuthe,chazaijika le-resonance,futhi unqumeinkambu kazibuthe resonance. Ububanzi bomugqa we-resonancekunqunywa ngokuya ngejika lokulinganisa, kanye nesikhathi sokuphumulaisampula ye-YIG polycrystalline iyalinganiselwa.

5. Isiginali ye-ferromagnetic resonance yebhola lekristalu elilodwa le-YIGisibonwa nge-oscilloscope, kanye nesiginali ye-resonance eyodwais okubonwa yi-phase shifter, ukuze kufundwe indlela yokunquma inkambu kazibuthe ene-resonant ngokubona kwe-oscilloscope.

6. Funda indlela yokukala ubude beza begagasi kanye nemvamisa ezwakalayo ye-resonant umgodinge-short-circuitipiston.

7. Iubudlelwano phakathi kwe-orientedinkambu kazibuthe ye-YIG eyodwa yesampula yekristalufuthi kukalwa, kanyeusayizi wei-resonance magnetic field ye-axis magnetization elula futhikanzimai-axis yamagnetization inqunywa. Ti-anisotropy njalo kanye ne-factor ibalwa.
