Unraveling the magnetism of a graphene triangular flake
Graphene is a diamagnetic material, this is, unable of becoming magnetic. However, a triangular piece of graphene is predicted to be magnetic. This apparent contradiction is a consequence of 'magic' shapes in the structure of graphene flakes, which force electrons to 'spin' easier in one direction. Triangulene is a triangular graphene flake, which possesses a net magnetic moment: it is a graphene nanometer-size magnet. This magnetic state opens fascinating perspectives on the use of these pure-carbon magnets in technology. (2020-05-11)

Scholes finds novel magnetic field effect in diamagnetic molecules

The researchers also detected low-intensity magnetic fields over the Borealis Basin, believed to be one of the oldest features on Mars. (2020-05-01)

The coexistence of vertical ferroelectricity and ferromagnetism with both Curie temperatures above room-temperature is predicted in ultrathin-layer CuCrS2 and CuCrSe2.A considerable net magnetization can be reversed upon a ferroelectric switching, where the change in spin-resolved band structure also renders efficient ''magnetic reading + electrical writing''.
