  • Ferromagnetic semiconductors that have the critical properties of semiconductors and ferromagnetism at room temperature have so far proven elusive. Here, by doping black phosphorus with Cobalt, Fu, Qu, Hou, Chang and coauthors induce ferromagnetism that persists up to room temperature, all while maintaining black phosphorus’ semiconducting properties.

  • While the electronic quality of graphene has significantly improved during the last two decades, charged defects inside encapsulating crystals still limit its performance. Here, the authors overcome this limitation and report the enhanced electronic quality of graphene enabled by tuneable Coulomb screening inside large-angle twisted bilayer and trilayer graphene devices, showing Landau quantization at magnetic fields down to ~5 mT.

  • Josephson vortices (JVs) play an important role in superconducting quantum devices, but they remain difficult to be observed and manipulated. Here, Dremov et al. report magnetic fingerprint of JVs in magnetic force microscopy experiments, which paves a way to generate and control JVs.
