Vanotsvagurudza vanobva kuNTNU vari kujekesa chiedza pamagineti pane zvidiki zviyero nekugadzira mafirimu nerubatsiro rwezvakawanda zvakajeka x-ray.
Erik Folven, Couritor of the oxical Boka kuNtnu's Dhipatimendi reNtnu neNtnu uye Ghenu uye Ghent Yunivhesiti Inoshanduka-fifoma micomagnets Basa racho, rakapihwa nechikamu neNTNU NANO uye kanzuru yekutsvagisa yeNorway, yakabudiswa mubhuku renhau yekudzokorora muviri.
Madiki emagineti
Einar akamira digyernes akagadzira madiki madiki emagineti anoshandiswa mukuedza.
Iyo madiki madiki magineti, yakagadzirwa na ntnu ph.D. Mumiriri einar akamira manhamba, angori maviri manhrometer yakakura uye akapatsanuka kuita mitezo mina, imwe neimwe ine mashiripiti akasiyana-siyana ekurongedza kana anti-wachi-wachi kutenderedza magneti.
Mune mamwe marudzi emagineti, mapoka madiki eatom band pamwe chete munzvimbo dzinonzi masiketi, umo magetsi ese emagetsi emagineti.
Munyika yeNTNU magneti, aya madhiri anosangana pane yepakati point-iyo vortex core-ipo iyo magineti manhamba mimwe mapoinzi zvakananga mukati kana kunze kwendege yezvinyorwa.
"Patinoshandisa munda wemaginhini, zvimwe nezvimwe zvikwangwani izvi zvichatongedzera munzira imwecheteyo," anodaro Felven. "Vanogona kukura uye vanogona kuderera, uye ipapo vanogona kubatana."
Elekitoni dzinenge dzichimhanya dzichimhanya
Kuona izvi zvichiitika hazvisi nyore. Vaongorori vakatora micomagns yavo kusvika 80m-yakafara donchrot, inozivikanwa seBessy II, muBerlin, uko maElectrons anokurudzirwa kusvikira vakurumidza kumhanya. Idzo dzinosimudzira-nzira dzinofamba-famba dzinobuda pachena x-rays.
"Isu tinotora aya X-ray uye tishandise sechiedza muMicroscope yedu," anodaro Felven.
Nekuti magetsi anofamba akatenderedza musicches muBunches akapatsanurwa nevaviri Nanoseconds, iyo X-rays yavanokuisa pamusana chaizvo.
Kuongorora kwekutakura X-ray microscope, kana stxm, inotora idzo x-rays kuti dzigadzire snapshot yezvinhu zvemhando yemagineti. Nekunhuhwirira uku snapshots pamwe chete, vatsvagiri vanogona kunyatsogadzira bhaisikopo rinoratidza kuti micmet inoshandura sei nguva.
Nekubatsira kweiyo stxm, vatinoshanda navo vanovhiringidza micmonemams nejira rezvazvino akaisa munda wemashiripiti, uye akaona doins inoshandura chimiro uye vortex core famba kubva pakati.
"Iwe une magwara mashoma kwazvo, uye iwe unobva azviita uye edza kuzvienzanisa sezvazvinogadzirisa," anodaro. Pashure pazvo, vakaona musimboti uchidzokera pakati-asi munzira ine mhepo, kwete tambo yakatwasuka.
"Ichaita rudzi rwekutamba kusvika pakati," anodaro Felvy.
Imwe inotsvedza uye yapera
Imhaka yekuti ivo vanodzidza mamiriro epitaxial, ayo anogadzirwa pamusoro peiyo substrate iyo inobvumira vaongorori kuti vatamire zvinhu zvacho, asi vaizovhara iyo X-rays mune stxm.
Kushanda muNtnu Nanolab, vaongorori vakagadzirisa dambudziko retsiva nekuviga micomagnet yavo pasi pekaroni yekuchengetedza mari yayo yemagineti.
Ipapo ivo vakanyatsoteerera uye vakanyatsotarisa pasi pepasi pevhu nechero yakatarisana neGallium ion kusvikira chete mutete mutete. Maitiro ekurwadza ekurwadziwa anogona kutora maawa masere pane sampuli-uye imwe yekutsvedza inogona kuperetera njodzi.
"Chinhu chinonyanya kukosha ndezvekuti, kana ukauraya maginisism, hatizive kuti tisati tagara muBerlin," anodaro. "Hunyengeri ndechekuti, chokwadika, kuunza zvinopfuura chimwe chete muenzaniso."
Kubva pane zvakakosha fizikisi kune ramangwana zvishandiso
Nekutenda zvakashanda, uye timu iyi yakashandisa sampuli yavo yakanyatsorongeka kuti chati ndedzipi micomagnet's Domain inokura nekupedza nguva. Ivo zvakare vaigadzira komputa kufungidzira kuti vanzwisise zviri nani mauto aive ari kubasa.
Uyezve kufambira mberi kwedu kuziva kwedu fizikisi, kunzwisisa kuti Magnetism anoshanda sei pakureba uye nguva zviyero zvenguva inogona kubatsira mukugadzira zvishandiso zvemberi.
Magneti Iyo magineti yekutarisira yeVortex Core uye Domain yeMicremnet, semuenzaniso, inogona kunge ichishandiswa kuendesa ruzivo muchimiro che0S uye 1s.
Vaongorori vava kuvanzika kudzokorora basa iri neanti-feromagnetic zvinhu, uko mambure emidziyo yemagineti yemagineti inokona. Izvi zvinovimbisa kana zvasvika pakukomberedza-mudzidziso, Feromagnic zvinogona kushandiswa kuita zvishandiso zvive izvo kana simba riripo, asi tribier kuti uongorore nekuti zviratidzo zvavanogadzira zvichave zvisina simba.
Pasinei nedambudziko irori, rakanyorova tariro. "Takafukidza pasi pekutanga nekuratidza isu tinogona kuita samples uye tarisiro kuburikidza navo ne-x-ray," anodaro. "Nhanho inotevera ichave yekuona kana tichigona kuita samples dzemhando yepamusoro yakakwana kuti uwane chiratidzo chakakwana kubva kune anti-feromagnetic zvinhu."
