LADP-4 Microwave Ferromagnetic Resonance Apparatus

Tsanangudzo Pfupi:

Ferromagnetic resonance inoita basa rakakosha mune magineti uye kunyange yakasimba nyika fizikisi.Ndiyo hwaro hwe microwave ferrite physics.Microwave ferrite yakashandiswa zvakanyanya mu radar tekinoroji uye microwave kutaurirana.Ichi chishandiso chemazuva ano chekuyedza chinoshandiswa kupedzisa dzidziso yekuyedza yeferromagnetic resonance curve kuyerwa kwemasampuli eferrite.Inonyanya kushandiswa kuyera resonance spectral mitsara yeYIG single crystal uye polycrystalline samples, kuyera g factor, spin magnetic ratio, resonance linewidth uye nguva yekuzorora, uye kuongorora maitiro e microwave system.Chiridzwa chine zvakanakira kuyerwa kwakaringana, yakagadzikana uye yakavimbika, yakapfuma yekuyedza yemukati uye zvichingodaro.Inogona kushandiswa kune vakuru vefizikisi 'nyanzvi kuyedza uye yemazuva ano kuyedza fizikisi.
