Zhe Wang, HZDR and S. Zherlitsyn, HLD Dresden Understanding quantum phase transitions, i.e., phase transitions at zero temperature driven by non-thermal parameters, has become one of the most significant topics in condensed-matter physics. It is generally believed that universal [...]

Sergio Pezzini & Uli Zeitler, HFML Nijmegen Using high magnetic-magnetic fields, the Bloch states in two-dimensional graphene superlattices can be influenced in a way that adding fractions of flux quanta into a superlattice unit cell lead to high temperature [...]

Layered materials can realize different stackings of their individual planes, different polytypes, to compose three-dimensional structures. ABA-stacked graphite is the most stable form of graphite at ambient conditions and the study of thin layers of this material [...]

Stevan Arsenijevič, HLD-HZDR Dresden and Nigel E. Hussey, HFML Nijmegen The thermoelectric effect (TE) in metals occurs as a voltage difference – accumulated charge – when a thermal gradient is applied. This property can be used to [...]

We report a 51V nuclear magnetic resonance investigation of the frustrated spin-1/2 chain compound LiCuVO4, performed in pulsed magnetic fields and focused on high-field phases up to 56 T. For the crystal orientations H∥c and H∥b, we find [...]

Antiferromagnets (AFMs) have attracted increasing attention in state-of-the-art research. Their important role in enhancing the hardness of ferromagnetic electrodes through the exchange-bias effect in microelectronics, has been broadly extended by new perspectives in spintronic applications. AFMs also facilitate current-induced [...]

Peter Christianen, HFML Nijmegen Single-layer transition-metal dichalcogenides, such as MoS2, MoSe2, WS2, WSe2, are two-dimensional semiconductors with a honeycomb lattice. Their band structures show a pair of inequivalent valleys (local extrema) at the +K and -K points of [...]
