Wata tawaga ce karkashin jagorancin Qiu Guangchun, farfesa a sashen kimiyya da fasaha na jami'ar aoyama Gakuin. Babban kayan aiki yana da zafin jiki mai canzawa zuwa sama kamar Tc = 39K (-234 ℃) lokacin da juriya ta saukad da sifili. Binciken ya sake yin rikodin rikodin don kayan aikin jan ƙarfe na jan ƙarfe Tc. Mista Akiko ya yi taron manema labarai a ranar 26 ga Fabrairu 2001 don sanar da sakamakon binciken. Yawancin cibiyoyin bincike a Japan da kasashen waje "sun kuma tabbatar da" wannan gaskiyar ta hanyar karin gwaje-gwaje (Cibiyar International for Superconducting Industrial Technology Institute of Superconductivity Second Research Director, Suko Tajima et al.). Mafi girman yanayin zafin yanayin canja wuri, mafi dacewar amfani shi ne. Tc na 39K ba shi da girma sosai.

A halin yanzu, mutane sun sami babban mai sarrafa zafin jiki (HgBa2Ca2Cu3O8) tare da Tc na 134K (-139 ℃). Gano sabon superconductor ya ja hankali saboda abun da ke ciki. A da, yawanci ana samun yanayin zafi ta hanyar jan karfe. Saboda sinadarin tagulla na aji ne na yumbu, yana da "wuya a sarrafa shi cikin siraran layi, saboda haka ba a yi amfani da shi ba har yanzu" (Qiu Guang) Idan aka kwatanta da wannan, sinadarin ƙarfe manganese diboride yana da fa'idodi masu zuwa.

(1) Manganese (Mg) da boron (B) suna da arha kuma ana samun su da sauki. "Wannan shine mafi kyawun haɗuwa don haɓaka masana'antu" (Lokacin kaka).
(2) Kamar yadda yanayin zafin jiki kira yake 700 ℃ kawai, don haka farashin masana'antu da sarrafawa yayi ƙarancin.
(3) conaƙƙarfan kayan aikin haɗin gami da ke ƙunshe da abubuwan ƙarfe na Mg da manganese diboride ba zai lalace ba ko da kuwa an sarrafa shi zuwa cikin yanayin haɗin.
(4) Kamar yadda abubuwa biyu kawai suka ƙunsa, yana da sauƙin haɗuwa zuwa ƙananan fina-finai.

Kayan yana kusa da SQUID (superconducting quant tsangwama na'urar) da ake buƙata.
