Izinsiza kusebenza ze-LADP-4 Microwave Ferromagnetic Resonance
I-resonance ye-Ferromagnetic idlala indima ebalulekile kukazibuthe ngisho naku-state physics eqinile. Kuyisisekelo se-microwave ferrite physics. I-Microwave ferrite isetshenziswe kabanzi kwezobuchwepheshe be-radar kanye nokuxhumana kwe-microwave. I-fd-fmr-a microwave ferromagnetic resonance ithuluzi lokuhlola elikhiqizwe yiShanghai Fudan Tianxin science and Education Instrument Co, Ltd. iyithuluzi lesimanje lokuhlola elisetshenziselwa ukuqedela imfundiso yokuhlola yesilinganiso sejika le-ferromagnetic resonance lamasampuli we-ferrite. Isetshenziselwa ukukala ulayini we-resonance spectral we-YIG single crystal and polycrystalline samples, measure g factor, spin magnetic ratio, resonance linewidth nesikhathi sokuphumula, nokuhlaziya izici zohlelo lwe-microwave. Ithuluzi linezinzuzo zesilinganiso esinembile, esizinzile futhi esinokwethenjelwa, okuqukethwe kokuhlola okunothile njalonjalo. Ingasetshenziselwa ukuhlolwa okuphezulu kwabafundi be-physics kanye nokuhlolwa kwanamuhla kwe-physics.
Ukuhlolwa
1.Bhekisisa imicrowave ferromagnetic resonance phenomena of ferromagnetic materials.
2. Linganisa ububanzi bomugqa we-ferromagnetic resonance (ΔH) wezinto ze-microwave ferrite.
3. Linganisa iLande's g-factor ye-microwave ferrite.
4. Funda ukuthi ungalusebenzisa kanjani uhlelo lokuhlola lwe-microwave.
* Abanye babone imiphumela yokuhlola ekhonjiswe ngakwesobunxele.
