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

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

Lifted Kramers spin degeneracy (LKSD) has been among the central topics of condensed-
matter physics since the dawn of the band theory of solids,. It underpins established practical …

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 …

Fundamental physical properties, such as phase transitions, electronic structures, and spin
excitations, in all magnetic ordered materials, were ultimately believed to rely on the …

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

In this work, we exhaust all the spin space symmetries, which fully characterize collinear,
noncollinear, and commensurate spiral as well as incommensurate spiral magnetism, etc …

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

We performed angle-resolved photoemission spectroscopy (ARPES) on hexagonal MnTe, a
candidate for an altermagnet with a high critical temperature (TN= 307 K). By utilizing photon …
