Ofufuza ku CRANN (Center for Research on Adaptive Nanostructures and Nanodevices), ndi School of Physics ku Trinity College Dublin, lero adalengeza kuti maginito opangidwa ku Center akuwonetsa kusintha kwachangu kwambiri komwe kunalembedwapo.
Gululo linagwiritsa ntchito makina a laser a femtosecond mu Photonics Research Laboratory ku CRANN kuti asinthe ndikusinthanso maginito azinthu zawo mu triliyoni wa sekondi imodzi, kuwirikiza kasanu ndi kamodzi kuposa mbiri yakale, komanso kuwirikiza zana kuposa liwiro la wotchi ya wotchiyo. kompyuta yanu.
Kupeza uku kukuwonetsa kuthekera kwazinthu za m'badwo watsopano wamakompyuta othamanga kwambiri komanso makina osungira deta.
Ofufuzawo adakwaniritsa liwiro lawo losasinthika lomwe silinachitikepo mu aloyi yotchedwa MRG, yomwe idapangidwa koyamba ndi gululo mu 2014 kuchokera ku manganese, ruthenium ndi gallium.Pakuyesaku, gululi lidagunda makanema owonda a MRG ndikuphulika kwa kuwala kwa laser kofiyira, kutulutsa mphamvu zama megawati osakwana 1 biliyoni pamphindikati.
Kusintha克瓦语kutentha kumasintha maginito著。子matengera chakhumi chofulumira kwambiri cha picosecond kuti mukwaniritse kusintha koyamba (1 ps = thililiyoni imodzi ya sekondi).Koma, chofunikira kwambiri, gululi lidazindikira kuti litha kusinthanso mawonekedwe 10 thililiyoni pamphindikati pambuyo pake.Uku ndiye kusinthanso kwachangu kwambiri kwa maginito komwe kunawonedwapo.
Zotsatira zawo zasindikizidwa sabata ino m'magazini otsogola a physics, Physical Review Letters.
Kupezekaku kumatha kutsegulira njira zatsopano zamakompyuta komanso ukadaulo wazidziwitso, chifukwa cha kufunikira kwa zida zamaginito pamsika uno.Zobisika muzinthu zathu zambiri zamagetsi, komanso m'malo akuluakulu a deta pamtima pa intaneti, zipangizo zamaginito zimawerenga ndikusunga deta.Kuphulika kwachidziwitso kwamakono kumapanga deta yambiri ndipo kumawononga mphamvu zambiri kuposa kale lonse.Kupeza njira zatsopano zogwiritsira ntchito mphamvu zogwiritsira ntchito deta, ndi zipangizo kuti zigwirizane, ndi ntchito yofufuza padziko lonse lapansi.
Chinsinsi cha kupambana kwa magulu a Utatu chinali kuthekera kwawo kukwaniritsa kusintha kwakukulu popanda mphamvu yamaginito.Kusintha kwachikhalidwe kwa maginito kumagwiritsa ntchito maginito ena, omwe amabwera pamtengo wa mphamvu ndi nthawi.Ndi MRG kusinthaku kudakwaniritsidwa ndi kutentha kwapang'onopang'ono, pogwiritsa ntchito kulumikizana kwapadera kwa zinthuzo ndi kuwala.
Ofufuza a Utatu Jean Besbas ndi Karsten Rode akukambirana njira imodzi ya kafukufukuyu:
"Zipangizo zamaginito zimakhala ndi makumbukidwe omwe angagwiritsidwe ntchito polingalira.Pakadali pano, kusintha kuchokera ku gawo limodzi la maginito 'logical 0' kupita ku 'logical 1' kwakhala kukusowa mphamvu komanso pang'onopang'ono.Kafukufuku wathu amayang'ana liwiro powonetsa kuti titha kusintha MRG kuchokera kudera lina kupita ku lina mu 0.1 picoseconds ndipo mochititsa chidwi kwambiri kuti kusintha kwachiwiri kungatsatire ma piccoseconds a 10 pambuyo pake, molingana ndi ma frequency a ~ 100 gigahertz - mwachangu kuposa chilichonse chomwe chawonedwa kale.
"Kupezaku kukuwonetsa luso lapadera la MRG yathu yolumikizana bwino ndi kupota kuti titha kuwongolera maginito ndi kuwala ndi kuwala ndi maginito pamiyeso yomwe sinakwaniritsidwe mpaka pano."
Pothirirapo ndemanga pa ntchito丫古卢lake, Pulofesa Michael Coey, wa Trinity School of Physics and CRANN, anati, “Mu 2014 pamene ine ndi gulu langa tidalengeza koyamba kuti tapanga alloy yatsopano ya manganese, ruthenium ndi gallium, yomwe imadziwika kuti MRG, sitinayambepo. amakayikira kuti zinthuzo zinali ndi kuthekera kodabwitsa kwa magneto-optical.
"Chiwonetserochi chidzatsogolera ku malingaliro atsopano a chipangizo chozikidwa pa kuwala ndi maginito omwe angapindule ndi kuwonjezeka kwakukulu kwa liwiro ndi mphamvu zowonjezera mphamvu, mwinamwake potsirizira pake kuzindikira chipangizo chimodzi cha chilengedwe chonse chokhala ndi kukumbukira pamodzi ndi ntchito zomveka.Ndizovuta kwambiri, koma tawonetsa zinthu zomwe zitha kutheka.Tikuyembekeza kupeza ndalama ndi mgwirizano wamakampani kuti tikwaniritse ntchito yathu.
