RUB physicists let magnetic dipoles interact on the nanoscale for the first time
Bochum, Germany (SPX) May 22, 2013
Physicists at the Ruhr-Universitat Bochum (RUB) have found out how tiny islands of magnetic material align themselves when sorted on a regular lattice - by measurements at BESSY II. Contrary to expectations, the north and south poles of the magnetic islands did not arrange themselves in a zigzag pattern, but in chains. "The understanding of the driving interactions is of great technological interest for future hard disk drives, which are composed of small magnetic islands", says Prof. Dr. Hartmut ... read more
