Observation of Altermagnetic Order Switching in Bulk MnTe by Polarized Neutron Diffraction
Zheyuan Liu, Shinichiro Asai, Shingo Takahashi +3
Altermagnetic order, characterized by the Néel vector, breaks time-reversal symmetry (TRS) even in the nonrelativistic limit. Although spin-polarized and anomalous transport phenom…
Observation of Switchable Chiral Magnons in an Altermagnet
Zheyuan Liu, Hodaka Kikuchi, Zijun Wei +8
Chiral magnons, the quanta of handed spin waves, transport spin angular momentum without energy loss due to Joule heating. The recently discovered altermagnets were proposed to hos…
Single-crystal growth and magnetic, magnetoelectric, and optical properties of ferroaxial-type SrMnNiTeO
Ryoya Nakamura, Shinichiro Asai, Yusuke Nambu +2
Single crystals of SrMnNiTeO, a member of the ferroaxial-type magnetic oxide family TeO ( = Pb, Sr; = Mn, Cd; = Ni, Co), have…
Kitaev interaction and proximate higher-order skyrmion crystal in the triangular lattice van der Waals antiferromagnet NiI2
Chaebin Kim, Olivia Vilella, Youjin Lee +14
Topological spin textures, such as magnetic skyrmions, are a spectacular manifestation of magnetic frustration and anisotropy. Most known skyrmion systems are restricted to a topol…
Fermionic Order by Disorder in a van der Waals Antiferromagnet
R. Okuma, D. Ueta, S. Kuniyoshi +11
CeTe3 is a unique platform to investigate the itinerant magnetism in a van der Waals (vdW) coupled metal. Despite chemical pressure being a promising route to boost quantum fluctua…
Low temperature magnetic properties of Nd2Ru2O7
S. T. Ku, Dinesh Kumar, M. R. Lees +9
We present magnetic susceptibility, heat capacity, and neutron diffraction measurements of polycrystalline Nd2Ru2O7 down to 0.4 K. Three anomalies in the magnetic susceptibility me…
