The DNA molecule, which is the support of the genetic information, is continuously altered within cells by endogenous and exogenous processes. Among these reactions that alter the structure of the biopolymer, the hydrolytic reactions are the most common. The latter processes lead to loss or ... More »
Atomically clean superconducting graphene has been grown on thin rhenium films. This breakthrough paves the way to new hybrid superconducting nanostructures.   Graphene is not an intrinsic superconductor but can become superconducting by proximity effect when it is intimately connected ... More »

In spintronics, the spin dependent transport properties of ferromagnets (Fs) lie at the heart of devices working principles. Conversely, antiferromagnets (AFs) are so far used for their magnetic properties only. However, spin dependent transport with AFs is of high interest: spin absorption lengths ... More »

In order to enhance the tunnel magnetoresistance (TMR) of magnetic tunnel junctions with perpendicular anisotropy the thicknesses of the electrodes on both sides of the MgO barrier have to be optimized. By carefully adjusting the thicknesses of the magnetic layers, taking into account a ... More »
