Abashakashatsi bo muri CRANN (Ikigo cy’ubushakashatsi kuri Adaptive Nanostructures na Nanodevices), hamwe n’ishuri rya fiziki muri Trinity College Dublin, uyu munsi batangaje ko aibikoresho bya rukuruziyatejwe imbere muri Centre yerekana uburyo bwihuta bwo guhinduranya ibintu byanditswe.
Itsinda ryakoresheje sisitemu ya lazeri ya femtosekond muri Laboratoire yubushakashatsi ya Photonics muri CRANN kugirango ihindure hanyuma yongere ihindure icyerekezo cya magnetiki yibikoresho byabo muri trillionths yisegonda, byikubye inshuro esheshatu kurenza ibyabanjirije, kandi byihuta inshuro ijana kurenza isaha yisaha mudasobwa bwite.
Ubu buvumbuzi bwerekana ubushobozi bwibikoresho kubisekuru bishya byingufu zikoresha mudasobwa yihuta cyane na sisitemu yo kubika amakuru.
Abashakashatsi bageze ku muvuduko wabo utigeze ubaho mu mavuta yiswe MRG, yashizwemo bwa mbere n'itsinda mu 2014 kuva manganese, ruthenium na gallium.Mu bushakashatsi, itsinda ryakubise firime ntoya ya MRG iturika rya lazeri itukura, itanga megawatt yingufu zitarenze miriyari yisegonda.
Ihererekanyabubasha rihindura icyerekezo cya magnetiki ya MRG.Bifata icya cumi cyihuta cya picosekond kugirango ugere kuriyi mpinduka yambere (1 ps = tiriyari imwe yisegonda).Ariko, icy'ingenzi, itsinda ryabonye ko rishobora guhindura icyerekezo cyongeye kugaruka kuri tiriyari 10 z'isegonda nyuma.Ubu ni bwo buryo bwihuse bwo kongera guhinduranya icyerekezo cya magneti.
Ibisubizo byabo byatangajwe kuri iki cyumweru mu kinyamakuru cya fiziki kiyobora, Amabaruwa asubiramo.
Ubuvumbuzi bushobora gufungura inzira nshya zo kubara no guhanga amakuru mu buryo bushya, ukurikije akamaro kaibikoresho bya rukuruzis muri uru ruganda.Hihishe mubikoresho byinshi bya elegitoroniki, ndetse no mubigo binini binini byamakuru hagati ya interineti, ibikoresho bya magneti bisoma kandi bikabika amakuru.Amakuru aturika kurubu atanga amakuru menshi kandi akoresha ingufu nyinshi kuruta mbere hose.Gushakisha ingufu nshya zokoresha uburyo bwo gukoresha amakuru, nibikoresho bihuye, nubushakashatsi bwisi yose.
Urufunguzo rwitsinda ryamakipe yubutatu nubushobozi bwabo bwo kugera kuri ultrafast guhinduranya nta murima wa magneti.Guhinduranya gakondo ya rukuruzi ikoresha urundi rukuruzi, ruza kubiciro ukurikije ingufu nigihe.Hamwe na MRG guhinduranya byagezweho hakoreshejwe ubushyuhe, hifashishijwe imikoreshereze idasanzwe yibikoresho n'umucyo.
Abashakashatsi b’Ubutatu Jean Besbas na Karsten Rode baganira ku nzira imwe y’ubushakashatsi:
“Ibikoresho bya rukuruzis mubusanzwe ufite kwibuka bishobora gukoreshwa muri logique.Kugeza ubu, kuva muri magnetiki imwe 'logique 0,' ukajya mubindi 'logique 1,' byashonje cyane kandi bitinda cyane.Ubushakashatsi bwacu bukemura umuvuduko twerekana ko dushobora guhindura MRG tuvuye muri reta tujya mubindi muri 0.1 picosekond kandi cyane cyane ko icya kabiri gishobora gukurikira picosekondi 10 gusa nyuma, gihuye numurongo wa ~ 100 gigahertz - byihuse kuruta ikindi kintu cyose cyagaragaye mbere.
Ati: "Ubuvumbuzi bwerekana ubushobozi bwihariye bwa MRG yacu bwo guhuza neza urumuri no kuzunguruka kugira ngo dushobore kugenzura magnetisme n'umucyo n'umucyo hamwe na magnetisme kugeza ubu bitagerwaho."
Porofeseri Michael Coey, Ishuri ry’Ubugenge ry’Ubutatu na CRANN, yagize icyo avuga ku bikorwa by’ikipe ye, yagize ati: “Mu mwaka wa 2014 ubwo jye n'itsinda ryanjye twatangaje bwa mbere ko twashizeho umusemburo mushya rwose wa manganese, ruthenium na gallium, uzwi ku izina rya MRG, ntabwo twigeze na rimwe ukeka ko ibikoresho byari bifite ubu bushobozi budasanzwe bwa magneto-optique.
Yakomeje agira ati: "Iyi myiyerekano izaganisha ku bikoresho bishya bishingiye ku mucyo na magnetisme bishobora kugirira akamaro umuvuduko mwinshi ndetse n’ingufu zikoreshwa, wenda amaherezo tukamenya igikoresho kimwe rusange gifite ububiko hamwe nibikorwa bya logique.Ni ikibazo gikomeye, ariko twerekanye ibikoresho bishobora gutuma bishoboka.Turizera kubona inkunga n'ubufatanye mu nganda kugira ngo dukore akazi kacu. ”
