LADP-3 Microwave Electron Spin Resonance Zvishandiso

Tsananguro Pfupi:


Chigadzirwa Chigadzirwa

Chigadzirwa Mateki

Electron spin resonance inonzi zvakare elektrononi paramagnetic resonance, iyo inoreva chiitiko chekushanduka kweronance pakati pemagineti esimba emagetsi eelectron spin magnetic nguva painokanganiswa neyakaenzana frequency frequency yemagetsi mu magnetic field. Ichi chiitiko chinogona kucherechedzwa muzvinhu zveparamagnetic zvine isina kuvharwa spin magineti nguva (kureva. Macomputer ane maelektroni asina kubatanidzwa). Naizvozvo, elektroni kutenderera resonance inzira yakakosha yekuona isina kusunganidzwa maerekitironi mune nyaya uye kusangana kwavo nemaatomu akapoterera, kuti vawane ruzivo nezve microstructure yechinhu. Iyi nzira ine kunzwisisika kukuru uye kugadzirisa, uye inogona kushandiswa kuongorora zvinhu zvakadzama pasina kukuvadza sampuro dhizaini uye pasina kupindira kumakemikari maitiro. Parizvino, inoshandiswa zvakanyanya mukutsvaga kwefizikisi, chemistry, biology uye mushonga.

 

Kuedza

1. Kudzidza uye kubvuma elektroni kutenderera resonance Fani.

2. Kuyera Lande's g-chinhu cheDPPH sampuro.

3. Dzidza mashandisiro ekushandisa microwave zvishandiso muEPR system.

4. Nzwisisa yakamira wave nekushandura resonant cavity urefu uye sarudza waveguide wavelength.

5. Measure yakamira wave wave shamba kugoverwa mune resonant mhango uye sarudza waveguide wavelength.
