High-energy spin excitations in the optimally doped Ba0.67K0.33Fe2As2
From our previous data on BaFe2As2 and BaFe1.9Ni0.1As2, one may assume that the superconductivity only affects the low energy excitations. But for Ba0.67K0.33Fe2As2, the doping... -
Spin dynamics of the Mn12 prototype nanomagnet fully unravelled by 4-dimensio...
Mn12, with an anisotropy barrier close to 65 K, has been for 20 years a prototype nanomagnet, but in spite of a number of investigations the actual link between the value of the... -
Unveiling the exotic quantum critical point in CeCu6-xAgx
The heavy fermion system CeCu6-xAux is arguably the most important (and studied) heavy fermion series which exhibits a quantum critical point. In recent years several new... -
