Bilayer orthogonal ferromagnetism in CrTe₂-based van der Waals system

Self-intercalated Chromium tellurides consist of CrTe₂ van der Waals layers, with additional Chromium atoms residing in the van der Waals gap. This highly tuneable class of magnetic materials has presented a range of unique magnetic phenomena, and here Bigi, Jego, Polewczyk et al add to this by showing that CrTe₂ (δ = 0.25 − 0.50) hosts orthogonal ferromagnetism.

The valley Nernst effect in WSe₂

Atomically thin transition metal dichalcogenides possess a valley degree of freedom, which could enrich the physics underpinning the conventional Nernst effect observed in traditional solids. Here, the authors report experimental evidence of the valley Nernst effect in WSe₂ at room temperature.

Evidence for spin-to-charge conversion by Rashba coupling in metallic states at the Fe/Ge(111) interface

Engineering the interaction between spin and charge is important for the creation of spintronics devices. Here, the authors show that the Rashba effect at a single crystalline Fe/Ge(111) interface produces enhanced spin-charge conversion, which could help develop a spin field-effect-transistor.

Helicity dependent photoresistance measurement vs. beam-shift thermal gradient

Many recent studies have explored the response of magnetic systems to circularly polarised light. To achieve this, typically experiments use a birefringent crystal. Here, Yang et al show that any small error in the alignment of the crystal can result in a beam shift, and this shift can lead to spurious signals similar yet unrelated to the electron spin.
