Magnetic manganese

A new manganese compound that is produced by tension in thin layers of the crystal structure of terbium manganese oxide is magnetic unlike the parent compound, according to its discoverers at the University of Groningen. Beatriz Noheda and colleagues explain that by ignoring the usually undesirable formation of domain walls, the team could generate new properties by allowing such walls to form during growth of thin layers. Noheda hopes that this new material might be exploited in sub-microscopic circuitry and in nanoscale reaction vessels.
