Materials for Tomorrow-Theory Experiments and Modelling--Ó¢ÎÄÔ°æ Nanotechnology also plays a decisive role in information technology. However, the rapid increase (doubling of the Internet traffic every 6 months, of the wireless capacities every 9 months and of the magnetic information storage every 15 months) cannot be compensated by a corresponding shrinkage of the semiconductor devices, as it was achieved in the past 30 years. To keep up with the demands, completely new devices have to be invented, operating on the nanoscale and exploiting quantum effects. One possibility is to use the spin of the electron in addition to its charge for information transmission and storage, i.e. going from conventional electronics to spintronics. The foundations of this technique, exploiting the giant magnetoresistance and the tunneling magnetoresistance are discussed from the experimental and theoretical point of view in the third contribution ×îÐÂÏÂÔØµØÖ·£º http://www.divshare.com/download/1878588-524 Ŀ¼·ÅÔÚ¸½¼þÀÈç¹û´ó¼Ò¸Ð¾õºÃµÄ»°£¬ÔÙÏÂÔØÒ²²»³Ù£¬Èç¹ûÄ㻹ÂúÒ⣬±ðÍüÁËÏò±ðÈËÍÆ¼ö£¡£¡Í¬Ê±¶¥Ò»Ï£¡£¡ [ Last edited by sxzhu on 2007-9-7 at 08:08 ] |
