That is too harsh @selinz, there is a several billion dollar industry based on GMR (giant magnetoresistance effect)...I am pretty certain you have a GMR based disk drive somewhere in your home...GMR has triggered the rise of a new field of electronics called spintronics which has been used extensively in the read heads of modern hard drives and magnetic sensors....what we are discussing here is whether you can make a logic circuit based on spintronics not whether spintronics is useful (it clearly is)...Kris
Spin devices are getting increasing attention, see for example recent emerging technologies symposium held in Vancouver last month (www.cmoset.com) and are posed to revolutionize charge based electronics we know...the key question remains when we will see these devices deployed in real world, commercial applications?

Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
