Vatsvagiri veCRNN (The Center for Research on Adaptive Nanostructures and Nanodevices), uye Chikoro cheFizikisi paTrinity College Dublin, nhasi vazivisa kutimagineti zvinhuyakagadziridzwa paCentre inoratidza inokurumidza magineti switching yakamborekodhwa.
Chikwata chakashandisa femtosecond laser masisitimu muPhotonics Research Laboratory kuCRANN kushandura uye nekuchinja zvakare magineti ekuona kwezvinhu zvavo mumatrillionths esekondi, katanhatu nekukurumidza kupfuura rekodhi yapfuura, uye nekukurumidza zvakapetwa kazana kupfuura kumhanya kwewachi. komputa yako pachako.
Kuwanikwa uku kunoratidza kugona kwezvinhu zvechizvarwa chitsva chesimba rinoshanda zvakanyanya-nekukurumidza makomputa uye masisitimu ekuchengetedza data.
Vatsvaguri vakawana kumhanyisa kusati kwamboitika mune alloy inonzi MRG, yakatanga kugadzirwa neboka muna 2014 kubva manganese, ruthenium uye gallium.Mukuyedza, timu yakarova mafirimu matete eMRG aine kuputika kwemwenje tsvuku, achiburitsa megawatts yesimba isingasviki bhiriyoni resekondi.
Kupisa kwekushisa kunoshandura kutaridzika kwemagineti kweMRG.Zvinotora chegumi chekukurumidza kusingafungidzike chepicosecond kuti uwane shanduko yekutanga iyi (1 ps = chidimbu chetrillionth chesekondi).Asi, zvinotonyanya kukosha, timu yakaona kuti vaigona kushandura maitiro zvakare 10 trillionths yesekondi gare gare.Uku ndiko kukurumidza kuchinjisazve kutariswa kwemagineti kwakamboonekwa.
Mhedzisiro yavo inoburitswa svondo rino mubhuku rinotungamira refizikisi, Physical Review Letters.
Kuwanikwa kwacho kunogona kuvhura nzira nyowani dzekuvandudza komputa uye ruzivo tekinoroji, zvichipihwa kukosha kwemagineti zvinhus muindasitiri iyi.Yakavigwa mune zvakawanda zvezvigadzirwa zvedu zvemagetsi, uyewo munzvimbo huru dze data pamwoyo we internet, magineti zvinhu zvinoverenga uye kuchengeta data.Ikozvino kuputika kwemashoko kunogadzira data yakawanda uye inoshandisa simba rakawanda kudarika kare.Kutsvaga nzira nyowani dzesimba dzekushandisa data, uye zvinhu kuti zvienderane, ibasa repasi rose rekutsvagisa.
Kiyi yekubudirira kwezvikwata zveTiriniti kwaive kugona kwavo kuwana shanduko yekukurumidza pasina kana magineti.Kuchinja kwechinyakare kwemagineti kunoshandisa imwe magineti, inouya nemutengo maererano nezvose simba uye nguva.NeMRG iyo switching yakawanikwa nekupisa kupisa, ichishandisa iyo yakasarudzika yekudyidzana nechiedza.
Vatsvagiri veTrinity Jean Besbas naKarsten Rode vanokurukura imwe nzira yetsvagiridzo:
“Magnetic zvinhus inherently ine memory iyo inogona kushandiswa kune logic.Kusvika pari zvino, kuchinja kubva kune imwe magineti yenyika 'zvinonzwisisika 0,' kuenda kune imwe 'inonzwisisika 1,' kwave kushuvira simba uye kunonoka.Tsvagiridzo yedu inogadzirisa kumhanya nekuratidza kuti tinokwanisa kushandura MRG kubva kune imwe nyika kuenda kune imwe mu 0.1 picoseconds uye zvakakosha kuti chechipiri switch inogona kutevera 10 picoseconds gare gare, inoenderana nekushanda frequency ~ 100 gigahertz - nekukurumidza kupfuura chero chinhu chakamboonekwa.
"Kuwanikwa kwacho kunoratidza kugona kwakakosha kweMRG yedu kunyatsobatanidza chiedza uye kutenderera kuitira kuti tigone kudzora magineti nechiedza uye nechiedza nemagnetism pane kusvika parizvino zvisingagoneke."
Vachitaura nezvebasa rechikwata chavo, Muzvinafundo Michael Coey, weTrinity’s School of Physics and CRANN, vakati, “Muna 2014 ini nechikwata changu patakatanga kutaura kuti takagadzira alloy nyowani yemanganese, ruthenium negallium, inozivikanwa seMRG, hatina kumbobvira tagadzira alloy itsva. akafungidzira kuti zvinhu izvi zvaive neiyi inoshamisa magneto-optical kugona.
"Chiratidziro ichi chinozotungamira kune mitsva yemuchina yakavakirwa pachiedza uye magineti inogona kubatsirwa nekuwedzera zvakanyanya kumhanya uye kushanda nesimba, pamwe pakupedzisira kuona imwe chete yepasirese mudziyo ine yakasanganiswa ndangariro uye zvine musoro kushanda.Idenho hombe, asi takaratidza zvinyorwa zvingaite kuti zvibvire.Tinovimba kuwana mari uye kubatana kwemaindasitiri kuti tiite basa redu.
