LADP-3 Microwave Electron Spin Resonance Ngwa
A na-akpọkwa resonance electron na-akpọ electron paramagnetic resonance, nke na-ezo aka na ntụgharị nke mgbanwe mgbatị n'etiti ike ike magnet nke elektrọn na-atụgharị oge mgbe ọ na-emetụta ụda ọkụ electromagnetic kwekọrọ na mpaghara magnet. Nke a onu nwere ike hụrụ na paramagnetic ihe na unpaired atụ ogho magnetik oge (ie ogige nwere uncoupled electron). Ya mere, ụda elegharịrị elektrọn bụ usoro dị mkpa iji chọpụta electron na-enweghị nsogbu n'okwu yana mmekọrịta ha na atọm ndị gbara ya gburugburu, iji nweta ozi gbasara microstructure nke ihe a. Usoro a nwere oke nghọta na mkpebi, enwere ike iji ya nyochaa ihe ahụ n'ụzọ zuru ezu na-emebi emebi usoro iheomume na enweghị nnyonye anya na mmeghachi omume kemịkal. Ka ọ dị ugbu a, a na-eji ya eme ihe na nyocha nke physics, kemistri, bayoloji na ọgwụ.
