Isixhobo se-Ferromagnetic Resonance se-LADP-4 Microwave se-LADP-4 Umfanekiso obonisiweyo

Izixhobo ze-Ferromagnetic Resonance ze-LADP-4 Microwave ze-LADP-4

Inkcazo emfutshane:

I-Ferromagnetic resonance idlala indima ebalulekileyo kwi-magnetism nakwi-solid state physics. Yiyo isiseko se-microwave ferrite physics. I-Microwave ferrite isetyenzisiwe ngokubhekiselele kwitekhnoloji ye-radar kunye nonxibelelwano lwe-microwave. Kwixesha lanamhlanje, i-ferromagnetic resonance, njenge-electron spin resonance kunye ne-magnetic resonance imaging, yindlela esebenzayo yokufunda iipropati ze-macroscopic kunye ne-microstructure yezinto.
Isixhobo se-microwave ferromagnetic resonance apparatus sakhiwe kakhulu ngamacandelo amathathu: inkqubo yomatshini oyintloko yovavanyo, inkqubo ye-microwave kunye nenkqubo ye-magnet. Ukongeza, kufuneka kuxhotyiswe i-dual trace oscilloscope (inxalenye ekhethiweyo) yovavanyo.

1. Ukuqonda nokuqonda imisebenzi kunye neendlela zokulawula isixhobo ngasinye se-microwave.

2. Qonda indlela eqikelelwa ngayoulungisoiimeko ezisemgangathweni kunye nezovavanyo ze-ferromagnetic resonance, kwaye uqonde iimpawu eziqhelekileyo ze-ferromagnetic resonance ngokujonga i-phenoi-menonye-ferromagnetic resonance.

3. Imiqondiso ye-Ferromagnetic resonance ye-YIG polycrystallineiibhola ziijongwe yi-oscilloscope ukumisela intsimi yemagnethi ye-resonance, kunye nomlinganiselo we-g factor kunye ne-gyromagnetic weesampuli ze-polycrystallineziibalwe ngokwexesha lokusetyenziswa kwe-microwave.

4.Ii-galvanometer yedijithaliisetyenziselwa ukulinganisa u-tulwalamano phakathi kwamandla okukhupha umgodi ojikelezayo kunye nentsimi yemagnethi,chazaijika le-resonance,kwaye umiseleintsimi yemagnethi evakalayoUbubanzi bomgca we-resonanceimiselwa ngokwendlela yokulinganisa, kunye nexesha lokuphumlaisampuli ye-YIG polycrystalline iqikelelwa.

5. Isignali ye-ferromagnetic resonance yebhola yekristale enye ye-YIGisibonwe yi-oscilloscope, kunye nesignali enye yesandiis ijongwe yi-phase shifter, ukuze ifunde indlela yokufumanisa i-resonant magnetic field ngokujonga i-oscilloscope.

6. Funda indlela yokulinganisa ubude be-waveguide kunye nobuninzi be-resonaumngxumange-short-circuitipiston.

7. Iulwalamano phakathi kwezinto ezijolise kuzointsimi yemagnethi ye-resonance yesampuli yekristale enye ye-YIGkwaye ilinganiswa, kwaye iubungakanani beintsimi yamagnetic ye-resonance ye-axis elula ye-magnetization kunyenzimai-axis yemagnetization imiselwe.Ti-anisotropy constant kunye ne-factor ziyabalwa.
