Abaphandi base-CRNN (Iziko loPhando kwi-Adaptive Nanostructures kunye ne-Nanodevices), kunye neSikole seFiziksi kwi-Trinity College Dublin, namhlanje babhengeze ukubaizinto zemagnethiiphuhliswe kwiZiko ibonisa olona tshintsho lukhawulezayo lwemagnethi lwakha lwarekhodwa.
Iqela lisebenzise iisistim ze-laser ze-femtosecond kwiLebhu yoPhando lweFotonics e-CRANN ukuze batshintshe kwaye baphinde batshintshe i-magnetic orientation yezinto zabo kwi-trillionths yesekhondi, ngokukhawuleza okuphindwe kathandathu kunerekhodi yangaphambili, kunye nekhulu eliphindwe ngokukhawuleza kunesantya sewotshi. ikhompyutha yakho.
Oku kufunyanisiweyo kubonisa amandla ezinto eziphathekayo kwisizukulwana esitsha samandla asebenzayo ekhompyutheni ngokukhawuleza kunye neenkqubo zokugcina idatha.
Abaphandi bafezekise isantya sabo sokutshintsha okungazange kubonwe ngaphambili kwi-alloy ebizwa ngokuba yi-MRG, eyaqala ukwenziwa liqela ngo-2014 ukusuka kwimanganese, i-ruthenium kunye ne-gallium.Kuvavanyo, iqela libethe iifilimu ezicekethekileyo ze-MRG ngokugqabhuka kokukhanya kwelaser ebomvu, ihambisa iimegawathi zamandla ngaphantsi kwebhiliyoni yesekondi.
Ukutshintshwa kobushushu kutshintsha i-magnetic orientation ye-MRG.Kuthatha ishumi leshumi elikhawulezayo lepicosecond ukufezekisa olu tshintsho lokuqala (1 ps = isigidi sesigidi sesigidi sesibini).Kodwa, okona kubaluleke kakhulu, iqela lifumanise ukuba lingatshintsha i-orientation kwakhona nge-10 yezigidigidi zesekondi kamva.Olu lolona tshintsho lukhawulezayo lokujikwa kwemagnethi ekhe yabonwa.
Iziphumo zabo zipapashwe kule veki kwijenali yefiziksi ehamba phambili, iileta zokuPhonononga iPhysical Review.
Ukufunyaniswa kunokuvula iindlela ezintsha zekhompyutha entsha kunye nethekhnoloji yolwazi, ngokunikwa ukubalulekaizinto zemagnethis kolu shishino.Ifihlwe kuninzi lwezixhobo zethu zombane, kunye nakumaziko amakhulu edatha esembindini we-intanethi, imathiriyeli yemagnethi ifundeka kwaye igcine idatha.Ukuqhuma kolwazi lwangoku kuvelisa idatha eninzi kwaye kudla amandla amaninzi kunanini ngaphambili.Ukufumana iindlela ezintsha zokonga amandla okusebenzisa idatha, kunye nemathiriyeli ukuze itshatiswe, luxakeko lophando lwehlabathi liphela.
Isitshixo kwimpumelelo yeqela likaBathathu Emnye yaba kukukwazi kwabo ukufezekisa ukutshintshwa kwe-ultrafast ngaphandle kwentsimi yemagnethi.Ukutshintsha umazibuthe ngokwemveli kusebenzisa enye umazibuthe, eza ngexabiso ngokwamandla kunye nexesha.Nge-MRG ukutshintshwa kwaphunyezwa nge-pulse yobushushu, kusetyenziswa ukusebenzisana okukodwa kwezinto kunye nokukhanya.
Abaphandi bakaBathathu Emnye uJean Besbas kunye noKarsten Rode baxoxa ngendlela enye yophando:
“Izinto zemagnetis ngokwendalo banenkumbulo enokusetyenziselwa ingqiqo.Ukuza kuthi ga ngoku, ukutshintsha ukusuka kwelinye ilizwe lemagnethi 'logical0,' ukuya kwenye 'logical 1,' ibilambe kakhulu amandla kwaye icotha kakhulu.Uphando lwethu lujongana nesantya ngokubonisa ukuba sinokutshintshela i-MRG ukusuka kwelinye ilizwe ukuya kwelinye kwi-0.1 picoseconds kwaye ngokubaluleke kakhulu ukuba ukutshintshwa kwesibini kunokulandela kuphela i-piccoseconds ye-10 kamva, ehambelana nokusebenza rhoqo kwe- ~ 100 gigahertz-ngokukhawuleza kunayo nayiphi na into ebonwe ngaphambili.
"Ukufunyaniswa kuqaqambisa isakhono esikhethekileyo se-MRG yethu yokudibanisa ngokufanelekileyo ukukhanya kunye nokujikeleza ukuze sikwazi ukulawula imagnethi ngokukhanya kunye nokukhanya ngemagnetism kumaxesha angenakufezekiswa okwangoku."
Ethetha ngomsebenzi weqela lakhe, uNjingalwazi uMichael Coey, weTrinity’s School of Physics and CRANN uthe, “Ngo-2014 xa mna neqela lam sabhengeza okokuqala ukuba senze ingxubevange entsha ngokupheleleyo yemanganese, iruthenium kunye negallium, eyaziwa ngokuba yiMRG Kukrokreleka ukuba i-material inala mandla amangalisayo wemagneto-optical.
“Lo mboniso uya kukhokelela kwiikhonsepthi ezitsha zesixhobo esekwe kukukhanya kunye nemagnethi enokuthi ixhamle ekwandeni kwesantya kunye nokusebenza kakuhle kwamandla, mhlawumbi ekugqibeleni iqonde isixhobo esinye sendalo esinenkumbulo edibeneyo kunye nokusebenza kwengqondo.Lucelomngeni olukhulu, kodwa siye sabonisa umbandela onokuthi wenze ukuba kwenzeke.Sinethemba lokufumana inkxaso-mali kunye nentsebenziswano kwishishini ukuze siqhubeke nomsebenzi wethu. ”
