Ua loaʻa i ka carbon nanotubes kekahi palapala noi. I kekahi mau lā i hala aku nei, ua paʻi ʻia kahi ʻatikala ma ka puke pai Nature Scientific Reports no ka manawa mua i noʻonoʻo i ka hiki ke hoʻohana i ka Multiwall carbon nanotubes (MWCNT) i ka hoʻopaʻa leo magnetic ma nā paʻakikī. ʻO kēia nāʻano likeʻole o nā hanana CNT paʻakikī i keʻano o "matryoshka dolls", "convolutions" a me nā hale'ē aʻe. ʻO ka hana i nā hihia a pau e iho mai i hoʻokahi mea - e hoʻopiha i kēlā me kēia carbon nanotube paʻakikī me nā nanoparticles magnetic. ʻAʻole hoʻokaʻawale kēlā me kēia nanoparticle magnetic i ka hopena hoʻopaʻa ʻikepili. Hiki iā ʻoe ke hoʻololi wale i ka magnetization o ka paipu holoʻokoʻa, akā e ʻoi aku ka paʻakikī ma mua o ke kākau ʻana i kahi kikowaena magnetic ma kahi pā HDD magnetic maʻamau. ʻOi aku ka paʻa.
ʻO ke aʻo ʻana o ka hoʻopaʻa leo magnetic ma MWCNT i hana ʻia e nā ʻepekema mai ke Kulanui o Alaska (Fairbanks) a me kekahi mau ʻoihana ʻepekema ʻē aʻe ma USA a me Czech Republic. ʻO kekahi o nā alakaʻi o ka papahana ʻo ia ka ʻepekema Czech ʻo Gunther Kletetschka. Hoʻomaopopo ka mea loea i nā ala i loaʻa no ka hoʻonui ʻana i ka hoʻopaʻa hoʻopaʻa ʻana ma nā disks magnetic HDD ʻaʻole like me ka wikiwiki o ka ulu ʻana o ka ʻikepili. No ka pale ʻana i ka ulu ʻana o ka ʻikepili, pono e hoʻonui ʻia ka nui o ka mālama ʻana o nā paʻakikī paʻakikī e 40% i kēlā me kēia makahiki, a i nā makahiki i hala iho nei ua ulu ʻia e 10-15% i kēlā me kēia makahiki. ʻO ka hoʻopaʻa ʻana me ka hoʻohana ʻana i nā paipu kalapona kalapona ka pane i nā pilikia o ka wā ʻike, akā e mau ana nā hana noiʻi nui no kēia.
ʻO ke kumu o ka ʻike ʻia ʻo nā nanotubes kalapona me nā nanoparticles magnetic i loko i ʻike ʻia i nā kahua electromagnetic o nā amplitudes like ʻole a me nā alapine like ʻole. Ma ke ala, ua hoʻokō ʻia ka hana ʻana o nā paipu kalapona i hoʻopiha ʻia me nā nanoparticles me ka hoʻohana ʻana i ka waiho ʻana i loko o kahi wahi kinoea - ʻaʻohe mea hou. I ka wā i hoʻohana ʻia ai kahi māla magnetic me ka alapine a hiki i ka 10 kHz, ʻaʻohe mea i loaʻa (ka hopena o ka conductivity o carbon nanotubes i hoʻopili ʻia), akā me ka piʻi ʻana o ke alapine ma luna o 10 kHz a me ka emi ʻana o ka amplitude kahua, ka hopena. o ka magnetization o ka carbon nanotube me magnetic nanoparticles i ala mai. Wahi a ka poʻe ʻepekema, ua ʻae ke kahua o waho me ka māla magnetic o kēlā me kēia ʻāpana, kahi i hiki ai ke hāʻawi i ka nanotube stable magnetization i kahi kuhikuhi.
ʻAʻole i loaʻa i nā ʻepekema nā manaʻo pehea a pehea e hana ai i ka hoʻopaʻa ʻana a me ka heluhelu ʻana i nā mīkini no ka hoʻopaʻa ʻana i ka ʻikepili ma ke ʻano o nā nanotubes kalapona, akā hoʻohiki lākou e hana maikaʻi ma kēia ʻaoʻao, no ka mea, ʻaʻole e emi iki ka ʻikepili.
