Chiral Antiferromagnetism from Momentum-Space Resonance in a 2D Semiconductor
R. Okuma, T. Ikenobe, Y. Fujisawa +28
Understanding the principles governing the emergence of chiral quantum phases is a fundamental challenge, not only for uncovering new mechanisms of quantum-state formation but also…
Highly fluctuating double- magnetic order in the van der Waals metal CeTe
Ryutaro Okuma, Yuita Fujisawa, Natsumi Maekawa +5
CeTe is a van der Waals antiferromagnet composed of magnetic [CeTe] layers coupled to highly conducting Te square nets. Its simple quasi-two-dimensional electronic…
Probing the real-space density of spin-entangled electrons
Federico Pisani, Leonie Spitz, Libor Vojáček +12
On the textbook example of an isolated antiferromagnetic Heisenberg dimer, we demonstrate that the magnetic form factor and the magnetic electron density distribution can be extrac…
Magnetic order and excitations in the magnetically intercalated van der Waals material CrNbSe
Ryota Yamaoka, Hiraku Saito, Yuki Settai +10
CrNbSe is a triangular lattice magnet in which magnetic Cr ions are intercalated to form triangular lattices between NbSe van der Waals layers stacke…
Versatile multi-q antiferromagnetic charge order in correlated vdW metals
Y. Fujisawa, P. Wu, R. Okuma +13
Following the discovery of graphene, interest in van der Waals (vdW) materials has surged; however, advancing physics beyond graphene requires quantum vdW materials platforms that…
Uncovering hidden Fermi surface instabilities through visualizing unconventional quasiparticle interference in CeTe3
B. R. M. Smith, Y. Fujisawa, P. Wu +14
The charge density wave (CDW) state is a widespread phenomenon in low-dimensional metals/semimetals. The spectral weight of the associated folded bands (shadow bands) can be an int…
Zero-point entropies of spin-jam and spin-glass states in a frustrated magnet
Chairote Piyakulworawat, Asiri Thennakoon, Junjie Yang +8
Thermodynamics studies of a prototypical quasi-two-dimensional frustrated magnet BaSnZnCrGaO where the magnetic Cr ions are arranged in a tri…
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…
Degenerate ground state in the classical pyrochlore antiferromagnet NaMn(CO)Cl
Kazuhiro Nawa, Daisuke Okuyama, Maxim Avdeev +5
In an ideal classical pyrochlore antiferromagnet without perturbations, an infinite degeneracy at a ground state leads to absence of a magnetic order and spin-glass transition. Her…
Superconductivity and non-Fermi-liquid behavior in the heavy-fermion compound CeCoNiIn
Ryo Otaka, Makoto Yokoyama, Hiroaki Mashiko +8
The effect of off-plane impurity on superconductivity and non-Fermi-liquid (NFL) behavior in the layered heavy-fermion compound CeCoNiIn is investigated by specific…
