LADP-4 Microwave Ferromagnetic Resonance Apparatus

Nā hoʻokolohua

1. Hoʻomaopopo a haku i nā hana a me nā ʻano hoʻoponopono o kēlā me kēia mīkini microwave.

2. Hoʻomaopopo i ka measurementkumu a me nā kūlana hoʻokolohua o ka ferromagnetic resonance, a hoʻomaopopo i nā ʻano maʻamau o ka ferromagnetic resonance ma ka nānā ʻana i ka phenomenono ka ferromagnetic resonance.

3. Nā hōʻailona ferromagnetic resonance o YIG polycrystallinepoepoe henānā ʻia e ka oscilloscope e hoʻoholo ai i ka resonance magnetic field, a me g factor a me gyromagnetic ratio o nā laʻana polycrystalline.hehelu ʻia e like me ke alapine microwave.

4.ʻO kagalvanometer kikohoʻehoʻohana ʻia e ana i ka tka pilina ma waena o ka mana hoʻopuka o ka lua resonant a me ke kahua magnetic,weheweheka piʻi ʻana o ka resonance,a hooholoke kahua mākia resonance. Ka laula laina resonanceua hoʻoholo ʻia e like me ke ana ʻana, a me ka manawa hoʻomahao YIG polycrystalline hāpana i manaʻo ʻia.

5. ʻO ka hōʻailona ferromagnetic resonance o YIG hoʻokahi pōlele anianiisʻike ʻia e ka oscilloscope, a me ka hōʻailona resonance hoʻokahiis ʻike ʻia e ka mea hoʻololi ʻāpana, i aʻo ai i ke ʻano o ka hoʻoholo ʻana i ke kahua magnetic resonant ma ka nānā ʻana o ka oscilloscope.

6. E aʻo i ke ana ʻana i ka nalu alakaʻi nalu a me ke alapine resonant o ka resonant luama ka pōkolepiston.

7. Kapili ma waena o orientedresonance magnetic field o YIG hoʻokahi kristal hāpanaa anaia, a me kanui oresonance magnetic field o ka axis magnetization maʻalahi apaakikiHoʻoholo ʻia ke axis magnetization. Thelu ʻia ka anisotropy mau a me ka helu.
