Van der Waals epitaxial growth of air-stable CrSe2 nanosheets with thickness-tunable magnetic order
CrSe2 nanosheets grown on WSe2 show no apparent change in surface roughness or magnetic properties after months of exposure in air. Calculations suggest that charge transfer from the WSe2 substrate and interlayer coupling within CrSe2 play a critical role.

Room-temperature antiskyrmions and sawtooth surface textures in a non-centrosymmetric magnet with S4 symmetry
Antiskyrmions had only been observed in a few Heusler compounds with D2d symmetry. Here a new material, Fe1.9Ni0.9Pd0.2P, in a different symmetry class (S4 symmetry) is reported to host antiskyrmions, as well as sawtooth surface textures and skyrmions.

Seebeck-driven transverse thermoelectric generation
Transverse thermeoelectrics can simplify devices as the electric field and heat gradient are perpendicular, but the power output is much less than in standard devices. Here, by forming a closed circuit of thermoelectric and magnetic materials, a much larger transverse thermopower is generated.

Tuning spin excitations in magnetic films by confinement
The thickness dependence of the dispersion of spin waves in mesoscopic iron films is measured and found to be renormalized in the out-of-plane direction as the thickness is reduced. The results are captured by a Heisenberg model that accounts for the confinement in the out-of-plane direction through the loss of Fe bonds.
