LADP-4 Microwave Ferromagnetic Resonance Apparatus

Liteko

1. Utloisisa le ho tseba mesebetsi le mekhoa ea taolo ea sesebelisoa ka seng sa microwave.

2. Utloisisa tekanyorementmolao-motheo le maemo a liteko a ferromagnetic resonance, le ho utloisisa litšobotsi tse akaretsang tsa ferromagnetic resonance ka ho shebella pheno.menonsebopeho sa ferromagnetic resonance.

3. Ferromagnetic resonance lipontšo tsa YIG polycrystallinelibolo bae bonoa ke oscilloscope ho fumana hore na matla a khoheli a resonance, le g factor le gyromagnetic ratio ea disampole tsa polycrystallinebae baloang ho latela maqhubu a microwave.

4.Thegalvanometer ea digitale sebelisetsoa ho metha tkamano pakeng tsa matla a tlhahiso ea cavity ea resonant le matla a khoheli,hlalosamokokotlo oa resonance,le ho etsa qetomatla a makenete a resonance. Bophara ba mohala oa resonancee khethoa ho ea ka lekhalo la tekanyo, le nako ea ho phomolaea YIG polycrystalline sampole e hakanngoa.

5. Letšoao la ferromagnetic resonance la YIG single crystal ballise bonoa ke oscilloscope, le lets'oao le le leng la resonanceis e shebiloeng ke phaseshier, e le ho ithuta mokhoa oa ho tseba matla a khoheli a resonant ka ho shebella oscilloscope.

6. Ithute ho lekanya waveguide wavelength le resonant frequency of resonant cavityka potoloho e khuts'oanepiston.

7. Thekamano pakeng tsa tse sekametsengresonance magnetic field ea YIG single kristale sampolele e lekantsoeng, le hoboholo baresonance magnetic field of easy magnetization axis leka thatamagnetization axis e ikemiselitse. To anisotropy kamehla le factor balwa.
