LADP-4 Microwave Ferromagnetic Resonance Apparatus

Fa'ata'ita'iga

1. Malamalama ma fa'atautaia galuega ma metotia fa'atonutonu o masini microwave ta'itasi.

2. Malamalama i le measutoe faamanatumataupu faavae ma tulaga faataitai o le ferromagnetic resonance, ma malamalama i uiga lautele o le ferromagnetic resonance e ala i le matauina o le phenomenono le ferromagnetic resonance.

3. Feromagnetic resonance faailoilo YIG polycrystallinepolo omata'ituina e le oscilloscope e fuafua ai le resonance maneta, ma le g factor ma le gyromagnetic ratio o polycrystalline samplesofa'atatau ile fa'avevela ole microwave.

4.O legalvanometer numerae fa'aaogaina e fua ai to le sootaga i le va o le malosi e gaosia ai le lua ma le maneta,faamatalale fua o le resonance,ma fuafuale maneta resonance. Le lautele laina resonanceua fuafuaina e tusa ai ma le fua curve, ma le taimi maloloole YIG polycrystalline fa'ata'ita'iga fa'atatau.

5. Le ferromagnetic resonance faailo o YIG tasi tioata tioataismatauina e le oscilloscope, ma le faailo o le resonance tasiis matauina e le vaega shifter, ina ia aʻoaʻoina le auala e fuafua ai le maneta resonant e ala i le mataʻituina o le oscilloscope.

6. A'oa'o pe fa'apefea ona fua le umi ole galu ma le fa'asolo o le resonantnt luae ala pupuupiston.

7. O lesootaga i le va orientedresonance maneta fanua o YIG tasi tioata faataitaigama ua fuaina, ma letele oresonance maneta fanua o faigofie maneta axis mafaigataua fuafuaina le axis magnetization. To le anisotropy tumau ma fa'ailoga ua fuafuaina.
