Matubhu eCarbon nanotubes akawana imwe nzira yekushandisa. Mazuva mashoma apfuura, Nature Scientific Reports yakaburitsa chinyorwa, kekutanga, chakaongorora mukana wekushandisa matubhu ecarbon nanotubes akawanda (MWCNTs) mukurekodha magineti pamadhiraivha akaomarara. Aya ndiwo marudzi akasiyana-siyana eCNT akaomarara muchimiro che "matryoshka dolls," "rolls," nemamwe magadzirirwo. Chinangwa mune zvese zviitiko chinobva kuchinhu chimwe chete: kuzadza imwe neimwe yematubhu ecarbon nanotube yakaoma kudaro nemagineti nanoparticles. Magineti nanoparticles ega ega haazoburitse chero mhedzisiro yekurekodha data. Kugadzika kwechubhu yese chete ndiko kunogona kuchinjwa, asi izvi zvicharamba zvakakora kupfuura kurekodha munda wemagineti. domain paHDD magnetic platter yenguva dzose. Yakanyanya kuomarara.
Chidzidzo chekurekodha kwemagineti paMWCNT chakaitwa nemasayendisiti anobva kuYunivhesiti yeAlaska (Fairbanks) nedzimwe nzvimbo dzakawanda dzesainzi muUSA uye Czech RepublicNyanzvi yesainzi yekuCzech Gunther Kletetschka mumwe wevatungamiri vechirongwa ichi. Anoti nzira dziripo dzekuwedzera huwandu hwekurekodha kwemadhisiki edhisiki (HDDs) hadzichaenderane nehuwandu hwekukura kwedata. Kuti kuderedzwa kukura kwedata, huwandu hwekuchengetera madhisiki edhisiki hunofanira kuwedzera ne40% pagore, uye mumakore achangopfuura, hwave huchikura pa10-15% pagore. Kurekodha machubhu emagetsi ecarbon kungave mhinduro kumatambudziko enguva yeruzivo, asi kuchine tsvakiridzo yakawanda ichiri kuda kuitwa.
Izvo zvakakosha zvekuwanikwa ndezvekuti kabhoni nanotubes ine magineti nanoparticles mukati akaoneswa kune emagetsi minda yemaamplitudes akasiyana uye ma frequency akasiyana. Nenzira, kugadzirwa kwekabhoni machubhu akaiswa nanoparticles akaitwa pachishandiswa deposition munzvimbo ine gasi - hapana chitsva. Pakaiswa magineti nefrequency inosvika gumi kHz, hapana chakaitika (iyo yepamusoro mhedzisiro ye conductivity yekabhoni nanotubes yakakanganiswa), asi nekuwedzera kwema frequency pamusoro pe10 kHz uye nekudzikira kwemunda amplitude, mhedzisiro yacho. yemagnetization yekabhoni nanotube ine magineti nanoparticles yakasimuka. Maererano nemasayendisiti, nzvimbo yekunze yakasvika mukubvumirana nemagnetic field yezvimwe zvikamu, izvo zvakaita kuti zvikwanise kupa nanotube yakagadzikana magnetization mune imwe nzira.
Masayendisiti haasati ave nemazano ekuti sei uye sei kugadzira kurekodha uye kuverenga nzira dzekurekodha data pane yakarongwa kabhoni nanotubes, asi vanovimbisa kushanda nemazvo munzira iyi, nekuti nekufamba kwenguva hakuzove ne data shoma.
