Abaphandi base-CRANN (Iziko loPhando kwi-Adaptive Nanostructures kunye ne-Nanodevices)， kunye neSikole seFiziksi kwiKholeji yeZiqu-zintathu eDublin, namhlanje babhengeze ukuba izinto eziphathekayo eziphuhliswe kwiZiko zibonisa ukguqulwa kwammagnetic ngokukhawuleza okurekhodiweyo。
Iqela lisebenzise iisistim ze-激光ze-飞秒kwiLebhu yoPhando lweFotonics e-CRANN ukuze batshintshe baze baphinde batshintshe i-磁定向yemathiriyeli yabo kwi-trillionths yesekhondi, ngokukhawuleza okuphindwe kathandathu kunerekhodi yangaphambili, kunye namaxesha alikhulu 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合金ebizwa ngokuba yi-MRG, eyaqala ukwenziwa liqela ngo-2014 ukusuka kwimanganese, i-钌kunye ne-镓。Kuvavanyo, iqela libethe iifilimu ezicekethekileyo ze-MRG ngokugqabhuka kokukhanya kwelaser ebomvu, ihambisa iimegawathi zamandla ngaphantsi kwebhiliyoni yesekondi。
Ukutshintshwa kobushushu kutshintsha i-磁定向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 kwakha kwabonwa。
Iziphumo zabo zipapashwe kule veki kwijenali yefiziksi ehamba phambili, iileta zokuPhonononga iPhysical Review。
Ukufumanisa kunokuvula inindlela ezintsha zekhompuyutha entsha kunye nobuchwepheshe bolwazi, kunikwe ukubaluleka kwezinto eziphathekayo kule shishini。Ifihlwe kuninzi lwezixhobo zethu zombane, kunye nakumaziko amakulu edatha esembindini we-intanethi, imathiriyeli yemagnethi ifundeka kwaye igcine idatha。Ukuqhuma kolwazi lwangoku kuvelisa idatha eninzi kwaye kudla amandla amaninzi kunanini ngaphambili。Ukufumana inindlela ezintsha zokonga amandla okusebenzisa idatha, kunye nemathiriyeli ukutshatisa, 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:
" Izixhobo zemagneti ngokwendalo zinenkumbulo enokusetyenziselwa ukuqiqa。Ukuza kuthi ga ngoku, ukutshintsha ukusuka kwelinye ilizwe lemagnethi 'logical0，' ukuya kwenye ' logical1，' ibilambele kakhulu amandla kwaye icotha kakhulu。Uphando lwethu lujongana nesantya ngokubonisa ukuba sinokutshintsha i-MRG ukusuka kwelinye ilizwe ukuya kwelinye kwi-0.1 picoseconds kwaye ngokubaluleke kakulu ukuba utshintsho lwesibini lunokulandela kuphela i-picoseconds ye-10 kamva, ehambelana nokusebenza rhoqo kwe-~ 100 gigaherz -ngokukhawuleza kunayo nayiphi na变成ebonwe ngaphambili。
"Ukufunyaniswa kuqaqambisa isakhono esikhethekileyo se-MRG yethu yokudibanisa ukukhanya kunye nokujikeleza ukuze sikwazi ukulawula imagnethi ngokukhanya kunye nokukhanya ng磁学kumaxesha angenakufezekiswa okwangoku "
Ethetha ngomsebenzi weqela lakhe, uNjingalwazi ummichael Coey, weTrinity 's物理学院和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 w磁光学。
" Lo mboniso uya kukhokelela kwiikhonsepthi ezitsha zesixhobo esekwe kukukhanya kunye nemagthi ezinokuzuza ekwandeni kwesantya kunye nokusebenza kakuhle kwamandla, mhlawumbi ekugqibeleni kuqondwe isixhobo esinye sendalo esinenkumbulo edibeneyo kunye nokusebenza kwengqondo。Lucelomngeni olukhulu, kodwa siye sabonisa umbandela onokuthi wenze ukuba kwenzeke。sininethemba lokufumana inkxaso-mali kunye nentsebenziswano kwishishini ukuze siqhubeke nomsebenzi wethu "
