#Graphene Enables World's Strongest Magnetic Field

Graphene--pure crystalline carbon atoms--are known to make better electronic chips, but could also enable higher density magnetic storage too, thanks to new magnetic properties revealed by these researchers. Look for graphene to begin replacing our aging silicon chip infrastructure within five years. RColinJohnson @NextGenLog

In this scanning tunneling microscopy image of a graphene nanobubble, the hexagonal two-dimensional graphene crystal is seen distorted and stretched along three main axes. The strain creates pseudo-magnetic fields far stronger than any magnetic field ever produced in the laboratory.

Here's what Berkeley Labs says about its own announcement: Graphene, the extraordinary form of carbon that consists of a single layer of carbon atoms, has produced another in a long list of experimental surprises...a multi-institutional team of researchers headed by Michael Crommie, a faculty senior scientist in the Materials Sciences Division at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and a professor of physics at the University of California at Berkeley, reports the creation of pseudo-magnetic fields far stronger than the strongest magnetic fields ever sustained in a laboratory – just by putting the right kind of strain onto a patch of graphene...
