Spiral spin-liquid on a honeycomb lattice
Shang Gao, Michael A. McGuire, Yaohua Liu +5
Spiral spin-liquids are correlated paramagnetic states with degenerate propagation vectors forming a continuous ring or surface in reciprocal space. On the honeycomb lattice, spira…
Tuning the Room Temperature Ferromagnetism in Fe5GeTe2 by Arsenic Substitution
Andrew F. May, Jiaqiang Yan, Raphael Hermann +2
In order to tune the magnetic properties of the cleavable high-Curie temperature ferromagnet FeGeTe, the effect of increasing the electron count through arsenic substit…
Revealing room temperature ferromagnetism in exfoliated FeGeTe flakes with quantum magnetic imaging
Hang Chen, Shahidul Asif, Matthew Whalen +11
Van der Waals material FeGeTe, with its long-range ferromagnetic ordering near room temperature, has significant potential to become an enabling platform for implementing n…
Spin Photovoltaic Effect in Magnetic van der Waals Heterostructures
Tiancheng Song, Eric Anderson, Matisse Wei-Yuan Tu +9
The development of van der Waals (vdW) crystals and their heterostructures has created a fascinating platform for exploring optoelectronic properties in the two-dimensional (2D) li…
A catastrophic charge density wave in BaFeAl
William R. Meier, Bryan C. Chakoumakos, Satoshi Okamoto +8
Charge density waves (CDW) are modulations of the electron density and the atomic lattice that develop in some crystalline materials at low temperature. We report an unusual exampl…
Tuning the flat bands of the kagome metal CoSn with Fe, In, or Ni doping
B. C. Sales, W. R. Meier, A. F. May +8
CoSn is a Pauli paramagnet with relatively flat d-bands centered about 100 meV below the Fermi energy Ef. Single crystals of CoSn lightly doped with Fe, In, or Ni are investigated…
Unusual exchange couplings and intermediate temperature Weyl state in Co3Sn2S2
Qiang Zhang, Satoshi Okamoto, German D. Samolyuk +7
Understanding the magnetism and its possible correlations to the topological properties has emerged as a forefront and difficult topic in studying magnetic Weyl semimetals. Co$_{3}…
