'Of great technical interest for future hard disk drives' Physicists at the Ruhr-Universität 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...

Nature Communications: New development for fast storage media An international team of researchers from Germany and the Netherlands has developed a new material for storage media. For the first time they enable the switching of so called spin currents at room temperature in a vertical magnetic field. This increases the storage density distinctly. The novel switches can be used, for example, as read heads in future hard discs or as bits in non-volatile random access memory devices (MRAM)....

Rotating magnetic moments: Applied Physics Letters reports Bochum's physicists led by Prof. Dr. Hartmut Zabel have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behavior of the spin pumping had previously only been predicted theoretically. The research team at the RUB has now succeeded in measuring the effect using ultrafast X-ray scattering with picosecond resolution. Through their rotation of the magnetic moments, the so-called magnetic...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
