X-ray reveals that metal-free carbon could become magnetic at room temperature (May 3, 2007)

For many years, the existence of magnetic carbon has remained an enigma.  Previous claims to have solved the mystery were subsequently disproved when it was found that magnetic metals like iron, nickel, etc, were probably present in the carbon samples. Recently,  Dr. Ohldag (Stanford Synchrotron Radiation Laboratory) and his colleagues have shown that pure carbon can be made permanently magnetic at room temperature after carrying out a series of careful measurements including scanning transmission X-ray microscopy, X-ray magnetic circular dichroism (XMCD), PIXE analysis (to check for contamination by magnetic metals), AFM, and MFM etc. The team found that the magnetic order originates only from the carbon p-electron system. For more information, see the paper, p-Electron Ferromagnetism in Metal-Free Carbon Probed by Soft X-Ray Dichroism", H. Ohldag et al., Phys. Rev. Lett., 98,187204 (2007).

Coherent X-ray speckle pattern of antiferromagnets: First results (May 3, 2007)

Recently, some very interesting research on magnetic noise from antiferromagnets has been published. Unlike ferromagnets, the characteristics of which have been studied for many years, antiferromagnets have remained a mystery because their internal structure was too fine to be measured.  Their internal order is on the same scale as the wavelength of X-rays, and therefore, X-ray photon correlation spectroscopy, which measures 'speckle' patterns, can give a unique ‘fingerprint’ of a particular magnetic domain configuration.  It was found that the domain wall motion is thermally activated at temperatures above 100 K, but not so at lower temperatures.  For more information, see the paper, "Direct measurement of antiferromagnetic domain fluctuations", O. G. Shpyrko, et al., Nature 447, 68 (2007).
 

Towards attosecond - observation of electron tunnelling (April 5, 2007)

Atoms become ions when exposed to extremely intense light.  The process is predicted to occur via tunnelling through the binding potential that is suppressed by the light field near the peaks of its oscillations.  Professor F. Krausz (Max Planck Institute of Quantum Optics in Garching, Germany) and his collaborators recently reported the real-time observation of this most elementary step in strong-field interactions, i.e., light-induced electron tunnelling.  The team used 250-attosecond pulses of UV radiation, and confirmed theoretical predictions about the tunneling process.  It was also found that the process lasted for several hundred attoseconds, depleting atomic-bound states.  This would suggest that the use of tunneling itself is feasible for probing short-lived, transient states of atoms or molecules, e.g., multi-electron excitation (shake-up) and relaxation (cascaded Auger decay) processes etc.  For more information, see the paper, "Attosecond real-time observation of electron tunnelling in atoms", M. Uiberacker et al., Nature, 446, 627 (2007).

Obituary - Theodore H. Maiman (May 5, 2007)

Theodore H. Maiman, the American physicist who made the first working laser, died on March 5, 2007 at the age of 79 from systemic mastocytosis in Vancouver, Canada, where he lived with his wife.  Maiman's laser, based on a synthetic ruby crystal grown by Dr. Ralph L. Hutcheson, was first operated on 16 May 1960 at Hughes Research Laboratories in Malibu, California. It is well-known that this breakthrough was based on the idea of employing artificial rubies as the active medium for the laser at a time when others were trying only various gases.  Dr. Maiman would have been aware of errors in their calculations.  Another key point is that he also used pulses of light to excite atoms in the ruby.  This was the ground-breaking first step to the modern pulse laser.  Although his paper on this wonderful discovery was unfortunately mistakenly rejected by Physical Review Letters, the shortened version was published in Nature (“Stimulated Optical Radiation in Ruby, T. H. Maiman, Nature, 187, 493 (1960)).  Dr. Maiman received the Japan Prize in 1987.  He is the author of a book entitled “The Laser Odyssey” (Laser Press, 2000). The New York Times (May 11, 2007) carries an obituary written by Douglas Martin.
 

Nanocenter opened at Brookhaven National Laboratory (May 1, 2007)

The Center for Functional Nanomaterials (CFN) has opened at Brookhaven National Laboratory, United States.  The CFN is dedicated to the fabrication and study of nanoscale materials, with an emphasis on atomic-level tailoring to achieve desired properties and functions.  The science at the CFN is organized around three scientific themes; (i) nanocatalysis, (ii) biological and soft nanomaterials, and (iii) electronic nanomaterials.  The official opening ceremony will be held on May 21.  For more information, visit http://www.bnl.gov/cfn/
 

First set of experiments at SOLEIL (March 22, 2007)

Recently, at the new French synchrotron facility, SOLEIL, the first experimental results have been obtained in spite of the technically difficult situation that is still preventing the beamline from functioning under normal operating conditions.  The absorption spectroscopic experiments were done on a kidney stone, which is an agglomerate of many different nanometer-scale crystalline materials.  For more information on the recent status of SOLEIL, visit http://www.synchrotron-soleil.fr/
