Carbon Joins the Magnetic ClubThe exclusive club of magnetic elements officially has a new member—carbon. Using a proton beam and advanced x-ray techniques, researchers at SLAC in collaboration with colleagues from the University of Leipzig in Germany have finally put to rest doubts about carbon's ability to be made magnetic. The results appeared in the May 4 edition of Physical Review Letters. Scientists have long suspected that carbon belongs on the short list of materials that can be magnetic at room temperature, but proof of that hypothesis has languished in controversy for nearly a decade. Since antiquity, magnetism has appeared to be a trick performed only by iron, nickel, cobalt and a handful of rare alloys. "In the past, some groups thought they had discovered magnetic carbon," said Hendrik Ohldag, the paper's lead author and staff scientist at the Stanford Synchrotron Radiation Laboratory (SSRL). "Unfortunately, they realized later that they were misled by small amounts of iron, cobalt or nickel in their samples." Read more... |

The tenets of Open Access are to grant anyone, anywhere and anytime free access to the results of scientific research. HEP spearheaded the Open Access dissemination of scientific results with the mass mailing of preprints in the pre-WWW era and with the launch of the arXiv preprint system at the dawn of the '90s. The HEP community is now ready for a further push to Open Access while retaining all the advantages of the peer-review system and, at the same time, bring the spiralling cost of journal subscriptions under control. Mele will present a plan for conversion to Open Access of HEP peer-reviewed journals, through a consortium of HEP funding agencies, laboratories and libraries intended to engage scientific publishers toward building a sustainable model for Open Access publishing that is as transparent as possible for HEP authors. Don't miss Demystifying Open Access this Monday at 4:15 p.m. in Panofsky Auditorium. Learn more... Correction:
