    Coexistence of a spin-glass phase with antiferromagnetism in an intercalated crystal produces a large exchange bias effect. This is due to the interplay of disorder and frustration.

    Spin–orbit torque in heavy metal/ferromagnet heterostructures is promising for all-electric control of magnetic memory, but has so far required an additional symmetry breaking in the design to switch perpendicular magnetization. Instead, a low symmetry at the interface can give rise to out-of-plane spin torque and switch the magnetization deterministically.

    In this work Qiu et al. demonstrate that the application of van der Waals technology to STM/STS will dramatically expand the capabilities of the latter, allowing STM/STS to investigate the structure, electronic properties and magnetism of 2D magnetic insulators at the atomic scale.

    Sequence-defined molecules are promising for data storage applications, but synthesizing long sequences is typically required to achieve a high data storage capacity. Here the authors synthesize a library of different sequence-defined tetramers and hexamers and demonstrate that mixtures of these short sequence-defined oligomers can store up to 64.5 bit.
