Two-dimensional materials exhibiting a weak interlayer van der Waals bonding provide the opportunity for mechanical exfoliation down to single atomic layers. While non magnetic two-dimensional materials, like transition metal dichalcogenides, offer a broad range of electronic properties [1], combining magnetism with the confinement of two dimensions opens up the potential of effective current control of magnetization [2]. We focus on metallic as well as insulating ferromagnetic and antiferromagnetic two-dimensional van der Waals materials, for which we have previously determined the temperature dependence of the anisotropies [3]. We measure the spin Hall magnetoresistance [4] to probe magnetization and the Néel vector in these systems. References: [1] Manzeli et al., Nat. Rev. Mater. 2, 17033 (2017), [2] Mak et al., Nat. Rev.
