Iron-rich lamellae in a semiconductor
(PHYSorg.com Physics)

There is often a pronounced symmetry when you look at the lattice of crystals: It doesn`t matter where you look-the atoms are uniformly arranged in every direction. This behavior would also be expected of a crystal, which physicists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the University of Warsaw and the Polish Academy of Sciences produced with a compound from an indium arsenide semiconductor spiked with iron. The material, however, did not adhere to perfect symmetry. The iron formed two-dimensional, lamellar-shaped structures in the crystal that were magnetic. In the long term, the result could be vital in understanding superconductors.
