Altermagnets are an emerging elementary class of collinear magnets. Unlike ferromagnets,
their distinct crystal symmetries inhibit magnetization while, unlike antiferromagnets, they …

Magnons in ferromagnets have one chirality, and typically are in the GHz range and have a
quadratic dispersion near the zero wave vector. In contrast, magnons in antiferromagnets …

Observations of the anomalous Hall effect in RuO 2 and MnTe have demonstrated
unconventional time-reversal symmetry breaking in the electronic structure of a recently …

The relativistic spin Hall effect and inverse spin Hall effect enable the efficient generation
and detection of spin current. Recently, a nonrelativistic altermagnetic spin splitting effect …

Electrons, commonly moving along the applied electric field, acquire in certain magnets a
dissipationless transverse velocity. This spontaneous Hall effect, found more than a century …

We studied the magnetic ordering of thin films and bulk crystals of rutile RuO 2 using
resonant x-ray scattering across the Ru L 2 absorption edge. Combining polarization …

We present a computational study of antiferromagnetic transition in RuO 2. The rutile
structure with the magnetic sublattices coupled with π/2 rotation leads to a spin-polarized …

The magnetic ground state of single crystalline RuO 2 was investigated by the muon spin
rotation and relaxation (μ SR) experiment. The spin precession signal due to the …

The anomalous Hall effect is a time-reversal symmetry-breaking magneto-electronic
phenomenon originally discovered in ferromagnets. Recently, ruthenium dioxide (RuO2) …

We demonstrate the emergence of a pronounced thermal transport in the recently
discovered class of magnetic materials—altermagnets. From symmetry arguments and first …
