    Fast field-driven antiferromagnetic spin dynamics is realized in ferrimagnetic Gd23Fe67.4Co9.6 thin films at the angular momentum compensation point. In particular, at this point, the field-driven domain wall mobility is found to be enhanced.

    Antiferromagnetic spintronics may pave the way to innovative information storage devices with perpendicular coupling, however experimental demonstrations are still sparse. Here, the authors demonstrate a graphene-mediated perpendicular antiferromagnetic coupling between Fe and Co layers in a Fe/graphene/Co sandwich structure.

    Beyond high resolving power, electron microscopy can be used to study both the electronic and magnetic properties of a sample. Here, Grillo et al. combine electron vortex beams with holographic detection to measure out-of-plane nanoscale magnetic fields.

    Engineering a coupling between magnetic molecules and conducting materials at room temperature could help the development of spintronic devices. Loh et al. show that the spin state of QDTP molecules deposited on graphene and MoS2 couples to their electronic structure, affecting magnetotransport.
