Manipulating the texture of magnetism

3 Feb 2012

Knowing how to control the combined magnetic properties of interacting electrons will provide the basis to develop an important tool for advancing spintronics: a technology that aims to harness these properties for computation and communication. As a crucial first step, Naoto Nagaosa from the RIKEN Advanced Science Institute, Wako, and his colleagues have derived the equations that govern the ...

Sunspots form due to magnetism, according to new theory

2 Feb 2012

Just in time for the sun’s busy season, scientists believe they may have figured out just what causes sunspots to appear on the surface of our very own star. It’s been known for some time that the spots appear darker because the area where the sunspot is located is cooler, giving it a darker appearance–but [...] Sunspots form due to magnetism, according to new theory is a post from: The Inquisitr
