Abaphandi abavela kwi-NTnu baphalaza izixhobo zemagnethi kwizikali ezincinci ngokudala iimovie zoncedo lwe-X-rays eqaqambileyo.
U-Erik Fideven, umlawuli we-EAFIK weqela le-Oxide kwiCandelo le-NTNU le-NTNU le-NTnu le-Elect, kunye noogxa kwiYunivesithi yaseNtnu kunye ne-Gheng eBelMagnets xa betshintsha njani i-magnetic subfic friul. Umsebenzi, oxhaswa ngemali yi-NTNU Nano kunye neBhunga loPhando laseNorway, yapapashwa kwiMpahla yoPhando lweMpahla.
Amagqwirha amancinci
I-Einar emilel imile ifakwe i-tistnets ye-tict esetyenziswe kuvavanyo.
Imagnethi encinci yesikwere, eyenziwe yi-NTNU PH.D. Umgqatswa we-Einar emiselweyo, yi-micrometer ezimbini nje ezibanzi kwaye zahlulwe zibe ngamabala amane enxantathu, nganye nganye ye-manytic upest ebonisa iwotshi yewotshi okanye i-anti-iwotshi ejikeleze iimagnethi.
Kwizixhobo ezithile zemagnethi, amaqela amancinci e-athomus kunye kwiindawo ezibizwa ngokuba zii-Domain, apho zonke ii-elektroniki zinesifundo esifanayo semagnetice.
Kwimazithi ye-NTNU, ezi ndawo zidibana kwindawo ephakathi-i-vortex ephambili - apho umzuzu wemagneti ubona ngqo ngaphakathi okanye ngaphandle kwendiza yendawo.
"Xa sisebenzisa umhlaba wemagneti, ngakumbi kwaye ezinye izinto ziya kuthi zenzele kwicala elinye," utsho uFolven. "Banokukhula kwaye banokuncipha, emva koko banokudibanisa omnye komnye."
I-elektroni phantse ngesantya sokukhanya
Ukubona le nto ingekho lula. Abaphandi bathatha i-micromagrognes yabo kwi-synchrotrotron engama-80, eyaziwa ngokuba yiBessy II, eBerlin, apho ii-elektroni ziyakhawuleziswa de zihambe phantse isantya sokukhanya. Ezo ze-eletroni ezihamba ngokukhawuleza emva koko zikhupha kakhulu i-X-rays.
"Sithatha le x-rays kwaye sizisebenzise njengokukhanya kwi-Microscope yethu," utsho u-Microscope.
Kungenxa yokuba i-elektroni ihamba ijikeleze i-synchrotron kwi-bunches ezahlulwe zii-nanosecond ezimbini, i-x-rays Ait ziza zingena kuphuphuma zichanekile.
Iskena sosulelo lwe-X-ray microscope, okanye i-stxm, ithatha loo nto i-x-ray ukwenza umfanekiso ofikayo wezinto ezibonakalayo zezinto zemagnethi. Ngokubhengeza ezi fitshops kunye, abaphandi banokudala imovie ebonisa ukuba i-MicroMagnet itshintshe kanjani ixesha.
Ngoncedo lwe-STNM, uFolven kunye noogxa bakhe baphazamisa i-micromagnets yabo enxibe i-purmating yangoku evelisa umhlaba owenzeyo, kwaye wabona imilo itshintsha imilo kunye ne-vortex core ivela kwiziko.
Uthi: Emva koko, babona ubuchwephesha bubuyela ephakathi kunye nendlela yomoya, hayi umgca othe ngqo.
"Kuya kudanisa ukubuyela kwiziko," utsho u-wilven.
Isiliphu esinye kwaye iphelile
Kungenxa yokuba bafunda izixhobo ze-pitatial, ezidalwe ngaphezulu kwendawo evumela abaphandi ukuba bakhuphe iipropathi zezinto, kodwa ziya kuthintela i-X-rays kwi-stm.
Ukusebenza kwi-NTnu Nanolab, abaphandi basombulule ingxaki enkulu ngokungcwaba i-micromagnet yabo phantsi komaleko wekhabhoni ukukhusela iipropathi zayo zemagner.
Emva koko ngononophelo kwaye ngokuguqula i-chiest the the primote phantsi kunye ne-gelium egxile kwi-gelium i-ions kude kube kuphela kwingqimba kakhulu. Inkqubo yepende inokuthi ithathe iiyure ezisibhozo kwisampulu-kunye nelinye i-slippe ipela intlekele.
"Into ebalulekileyo kukuba, ukuba ubulala i-magnetism, asiyi kwazi ukuba ngaphambi kokuba sihlale eBerlin," utshilo. "Iqhinga, kunjalo, ukuzisa ngaphezulu kwesampulu enye."
Kwifizisi esisiseko kwizixhobo zexesha elizayo
Ngombulelo, kwaye iqela lasebenzisa iisampulu zazo ezilungiselelwe ngononophelo ukuze itshatise ukuba i-micromagnet ikhule kwaye inyibilike ixesha. Baye badala i-computer yokuphononongwa ngcono ukuba bathini na umsebenzi.
Kunye nokuqhubela phambili ulwazi lwethu ngeFiziksi ezisisiseko, ukuqonda ukuba isebenza njani kwezi zinto zibanzi kunye nezikali zexesha elinokuba luncedo ekwenzeni izixhobo zexesha elizayo.
I-magnetim sele isetyenziselwa ukugcina idatha, kodwa abaphandi okwangoku bafuna iindlela zokuxhaphaza ngakumbi. I-Magnetic Actions ye-Portex Core kunye ne-domain ye-Micromagnet, umzekelo, inokuba isetyenziselwa ukwenza ulwazi ngohlobo lwe-0 kunye ne-1s.
Abaphandi ngoku bajolise ekuphindisweni lo msebenzi ngezinto ezichasene ne-ferroomagnetic, apho isiphumo somnatha wemizuzu yemagneti yemagneti iyacima. Oku kuyathembisa xa kufikwa kwithiyori, izixhobo ze-anti-ferromagnetic zinokusetyenziswa ukwenza izixhobo ezincinci kwaye zihlale zihlale zilahlekile ngenxa yokuba imiqondiso abayivelisayo iya kuba buthathaka kakhulu.
Ngaphandle kolo celomngeni, uFolven unethemba. "Sigubungele umhlaba wokuqala ngokubonisa ukuba sinokwenza iisampulu kwaye sizijonge ngee-X-rays," utshilo. "Inyathelo elilandelayo liya kuba libona ukuba le nto sinokwenza iisampulu zodidi oluphezulu ngokwaneleyo ukuze ufumane umqondiso owaneleyo ovela kwizinto ezichasene ne-anti-ferroomagnetic."
Ixesha lokuposa: ngo-May-10 ukuya ku-1121
