ON THE POSSIBILITY OF MAGNETORESISTANCE GOVERNED BY LIGHT

It has been shown that it is possibility to control magnetoresistance by light. The use of light-sensitive banana-shape molecules has been suggested as an engine for varying the thickness or spacer between the magnetic layers. The spacer is lled by a conducting polymer with copper-like conductivity (with inserted bent molecules), ensuring the proper interlayer exchange coupling, which is necessary for transition from a ferromagnetic to an anti-ferromagnetic ordering (and inverse) when the thickness of the spacer changes.
Keywords: magnetoresistance, banana-shape molecule, conducting polymer.

Great work! This is the type of information that should be shared around the internet. Shame on the search engines for not positioning this post higher! Come on over and visit my website . Thanks =)
My developer is trying to convince me to move to .net from PHP. I have always disliked the idea because of the costs. But he’s tryiong none the less. I’ve been using WordPress on numerous websites for about a year and am anxious about switching to another platform. I have heard fantastic things about blogengine.net. Is there a way I can import all my wordpress posts into it? Any kind of help would be really appreciated!
