A New Spin on Wireless Electronics

Posted October 11, 2011 7:00 AM

Nanoscale spin waves could replace microwave technology in tomorrow's wireless devices, according to some scientists. Now, researchers for the first time have been able to tie together theories with tangible observations. Using a specialized microscope, the team was able to visually express the propagation of spin waves from magnetic nano-contacts (see video). This opens up a potential pathway to replacing microwaves with a smaller, cheaper, and less resource-taxing technology. What's your view?

The preceding article is a "sneak peek" from Lab Equipment, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Lab Equipment today.

Can't watch Youtube stuff at work, please make a more descriptive definition of things like: "specialized microscope" or "replacing microwaves with a smaller technology" or, for the layman like me, who probably knows what is magnetic, nano and contact, but can't recall of a "magnetic nano-contact".

Thank you in advance

Scaling down transistors in an integrated circuit is approaching hard limits. Smaller transistors are leakier, until they stop working right. Packing them into smaller and smaller space produces too much heat.

The last few years very basic research is going on, to replace the transistor as we know it, with one where an electron's spin (a quantum mechanical value named spin) is the controlling factor. Promises to need less power, promises to run on much smaller space. That's it! Fundamental research at this point.
