Sesebelisoa sa ho toloka sa Ferromagnetic sa MAekerofounu sa LADP-4

Tlhaloso e Khutšoanyane:

Ho hlaka ha ferromagnetic ho bapala karolo ea bohlokoa ho makenete esita le fisiks ea boemo bo tiileng. Ke motheo oa fisiks ea microwave ferrite. Ferrite ea microwave e sebelisitsoe mabapi le theknoloji ea radar le puisano ea microwave. Mehleng ea kajeno, ho hlaka ha ferromagnetic, joalo ka ho hlaka ha electron spin le ho nahana ka ho hlaka ha magnetic resonance, ke mokhoa o sebetsang oa ho ithuta thepa ea macroscopic le sebopeho sa microscopic sa thepa.
Sesebelisoa sa microwave ferromagnetic resonance se entsoe haholo-holo ka likarolo tse tharo: sistimi e kholo ea mochini oa liteko, sistimi ea microwave le sistimi ea makenete. Ho phaella moo, oscilloscope e nang le trace e habeli (karolo e khethiloeng) e tla hlomelloa bakeng sa teko.
