Hologram Industry News

A recent edition of Nature journal reveals how collaboration between scientists in the U.S. and the U.K. has led to a major breakthrough in the understanding of antiferromagnets. Scientists at the Center for Nanoscale Materials at Argonne National Laboratory, the University of Chicago and the London Center for nanotechnology have exploited a technique called “X-ray photon correlation spectroscopy,” to see the internal workings of antiferromagnets, such as the metal chromium, for the very first time.
Gabriel Aeppli, director of the London Centre for Nanotechnology, said, “We haven’t been able to make the same strides forward with antiferromagnets because, until relatively recently, we couldn’t look inside them to see how they were ordered. ”
The internal order of antiferromagnets is on the same scale as the wavelength of X-rays — below 10 nanometres — and these have now been used to produce a `speckle’ pattern which is actually a hologram, or more loosely speaking, a unique fingerprint of a particular magnetic domain configuration.
The new experiments thus help to open the prospect of exploiting antiferromagnets in emerging technologies such as quantum computing.
