Spin Transport in Multi Wall Carbon Nanotubes with Co Electrodes

Chinese Physics Letters 2006年第10期23卷 2852-2855页

作者：王天兴魏红祥韩秀峰 R.M.Langford martin thornton M.A.Bari J.M.D.Coey State Key Laboratory of Magnetism Beijing National Laboratory for Condensed Matter Physics Institute of Physics Chinese Academy of Sciences Beijing 100080 Department of Physics Trinity College Dublin 2 Ireland

The magnetic field dependent transport behaviour of Co contacted multi-wall nanotubes is investigated. A sample with three Co electrodes has been measured by two-channel method with an in-plane magnetic field. When the in-plane magnetic field is perpendicular to the tube, high positive magnetoresistance up to 30% is obtained at low temperature from 3 K to 25K and with field parallel to the tube, negative magnetoresistance up to 15% is observed only from the high resistance junction. The detailed positive and negative magnetoresistance behaviour also changes with temperature.
