Antiferromagnetic Coupling in Magnetic Semiconductor

November 25th, 2008 / 1 Comment

Researchers working at NIST...
NIST, Korea University and University of Notre Dame researchers have observed this property for the first time, detailed in the paper Carrier-mediated antiferromagnetic interlayer exchange coupling in diluted magnetic semiconductor multilayers Ga1-xMnxAs/GaAs:Be.

Look for this to be published in Physical Review Letters.

An orb weaving spider playing around in Space
The spider and butterfly payload sent into space, project by the University of Colorado at Boulder, is an attempt to determine how weightlessness affects the behavior of these creatures. K-12 students in Colorado and Texas are comparing their own spiders and butterflies to those that are in space.

This will provide many an opportunity to [...]
