Spin-loss mechanisms in organic spin valves - separating interfacial and bulk contributions

Understanding the transfer of spin polarisation in real device structures remains one of the most difficult challenges in spintronics. A Swiss-UK team of researchers, lead by QMUL, performed the first ever depth-resolved measurement of the spin polarisation of current-injected charge carriers in a spin valve.

New insights into the glass transition

"Despite its apparent simplicity, understanding liquid-glass transition has defied the previous efforts of theorists, and has become has become one of the "most interesting unsolved problem in solid state theory", according to eminent scientists. The main problem of glass transition has been to explain the origin of heat capacity jump at the glass transition temperature Tg.
