Ma carbon nanotubes apeza ntchito ina. Masiku angapo apitawo, nkhani ina inasindikizidwa mu nyuzipepala Nature Scientific Reports kuti kwa nthawi yoyamba analingalira kuthekera kwa Multiwall carbon nanotubes (MWCNT) mu kujambula maginito pa hard drive. Izi ndi mitundu yosiyanasiyana ya zovuta za CNT monga "zidole za matryoshka", "convolutions" ndi zina. Ntchito muzochitika zonse imatsikira ku chinthu chimodzi - kuyika chilichonse chovuta kaboni nanotube chokhala ndi maginito nanoparticles. Maginito aliwonse a nanoparticle pawokha sangapange kujambula kwa data. Mutha kusintha maginito a chubu chonsecho, koma idzakhala yolimba kuposa kulemba gawo la maginito pa mbale yokhazikika ya maginito ya HDD. Kwambiri denser.
Kafukufuku wojambula maginito pa MWCNT adachitidwa ndi asayansi ochokera ku yunivesite ya Alaska (Fairbanks) ndi mabungwe ena asayansi ku USA ndi Czech Republic. Mmodzi mwa atsogoleri a polojekitiyi anali wasayansi waku Czech Gunther Kletetschka. Katswiriyu akuti njira zomwe zilipo zowonjezerera kuchuluka kwa kujambula pa HDD maginito disks sizikugwirizananso ndi liwiro la kukula kwa deta. Kuti muchepetse kukula kwa data, kachulukidwe kasungidwe ka ma hard drive amayenera kukula ndi 40% chaka chilichonse, ndipo m'zaka zaposachedwa wakhala akukula ndi 10-15% pachaka. Kujambula pogwiritsa ntchito machubu a carbon maginito kungakhale yankho ku zovuta za nthawi ya chidziwitso, koma ntchito yaikulu yofufuza iyenera kuchitidwa pa izi.
Chofunikira pakuzindikira ndikuti ma carbon nanotubes okhala ndi maginito nanoparticles mkati adawonekera kumadera amagetsi amagetsi amitundu yosiyanasiyana komanso ma frequency osiyanasiyana. Mwa njira, kupanga machubu a kaboni odzaza ndi nanoparticles kunachitika pogwiritsa ntchito malo okhala ndi mpweya - palibe chatsopano. Pamene mphamvu ya maginito idagwiritsidwa ntchito pafupipafupi mpaka 10 kHz, palibe chomwe chinachitika (pamtunda wa conductivity wa carbon nanotubes wakhudzidwa), koma ndi kuwonjezeka kwafupipafupi pamwamba pa 10 kHz ndi kuchepa kwa matalikidwe am'munda, zotsatira zake. za maginito a carbon nanotube ndi maginito nanoparticles anawuka. Malinga ndi asayansi, gawo lakunja linagwirizana ndi mphamvu ya maginito ya tinthu tating'onoting'ono, zomwe zinapangitsa kuti zitheke kupatsa nanotube magnetization yokhazikika m'njira yopatsidwa.
Asayansi alibebe malingaliro amomwe angapangire njira zojambulira ndi kuwerenga zojambulira deta pamitundu yambiri ya carbon nanotubes, koma amalonjeza kuti azigwira bwino ntchito iyi, chifukwa pakapita nthawi sipadzakhalanso data yocheperako.
