Magnetism is one of the largest, most fundamental, and technologically most relevant fields
of condensed-matter physics. Traditionally, two basic magnetic phases have been …

Recent developments have introduced a groundbreaking form of collinear magnetism
known as “altermagnetism”. This emerging magnetic phase is characterized by robust time …

Altermagnets feature vanishing net magnetization, like antiferromagnets, but exhibit time-
reversal symmetry breaking and momentum-dependent spin-split band structures. Motivated …

Recent series of theoretical and experimental reports have driven attention to time-reversal
symmetry-breaking spintronic and spin-splitting phenomena in materials with collinear …

Altermagnetism is introduced as a category of magnetic states with 'collinear'
antiferromagnetic spins and alternating variations of local structures around spins in such a …

Inelastic neutron scattering provides a powerful probe of the magnetic excitations of
quantum magnets. Altermagnets have recently emerged as a new class of magnets with …

We propose a minimal toy model for a two-dimensional altermagnet. The model unravels
altermagnetic properties at a microscopic level. We find spin-split electron and …

Altermagnetism is a recently identified magnetic symmetry class combining characteristics of
conventional collinear ferromagnets and antiferromagnets, that were regarded as mutually …

The combined rotational and time-reversal symmetry breakings that define an altermagnet
lead to an unusual d-wave (or g-wave) magnetization order parameter, which in turn can be …

We show that time-reversal symmetry-broken, centrosymmetric antiferromagnets with
nonrelativistic spin splitting of d-wave symmetry—the so-called d-wave altermagnets—are …
