Nano magnets arise at 2-D boundaries
Houston TX (SPX) Nov 18, 2013
When you squeeze atoms, you don't get atom juice. You get magnets. According to a new theory by Rice University scientists, imperfections in certain two-dimensional materials create the conditions by which nanoscale magnetic fields arise. Calculations by the lab of Rice theoretical physicist Boris Yakobson show these imperfections, called grain boundaries, in two-dimensional semiconducting materials known as dichalcogenides can be magnetic. This may lead to new strategies for the growing field of ... read more
