Mudziyo weFerromagnetic Resonance weLADP-4 Microwave

Tsananguro pfupi:

Ferromagnetic resonance ine basa rakakosha mumagnetism uye kunyange solid state physics. Ndiyo hwaro hwe microwave ferrite physics. Microwave ferrite yave ichishandiswa pakushandisa radar technology uye microwave communication. Munguva dzazvino, ferromagnetic resonance, senge electron spin resonance uye magnetic resonance imaging, inzira inoshanda yekudzidza macroscopic properties uye microstructure yezvinhu.
Muchina we microwave ferromagnetic resonance unonyanya kuumbwa nezvikamu zvitatu: sisitimu yemuchina wekuyedza, sisitimu ye microwave uye sisitimu yemagnet. Pamusoro pezvo, dual trace oscilloscope (chikamu chisingadiwi) inofanira kunge yakagadzirirwa kuyedza.

1. Nzwisisa uye ziva mashandiro uye nzira dzekudzora dzemudziyo wega wega we microwave.

2. Nzwisisa chiyerokugadzirisamamiriro ekusimbisa uye ekuyedza e ferromagnetic resonance, uye kunzwisisa hunhu hwe ferromagnetic resonance nekutarisa phenomenonye ferromagnetic resonance.

3. Zviratidzo zveFerromagnetic resonance zveYIG polycrystallinemabhora variinoonekwa ne oscilloscope kuti ione resonance magnetic field, uye g factor uye gyromagnetic ratio yema polycrystalline samplesvarizvakaverengerwa zvichienderana nehuwandu hwe microwave.
