Volatile resistive-switched state in a bulk organic conductor with a sharp metal-insulator transition
Riku Ishii, Ryo Motohashi, Keitaro Tada +6
Volatile resistive switching in correlated-electron systems, characterized by an abrupt resistance decrease under applied current, is crucial for developing next-generation electro…
Dipolar-driven mean-field criticality in the ferrimagnet EuMnSiO
Masahiro Kawamata, Maxim Avdeev, Yusuke Nambu
We report mean-field critical behavior in EuMnSiO, a melilite-type ferrimagnet with spin-only Eu and Mn moments and negligible orbital contributions. Magn…
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…
Magnetic excitations in the noncentrosymmetric magnet Sr2MnSi2O7
Masahiro Kawamata, Xiaoqi Pang, Hiroshi Murakawa +7
Magnetic excitations in the noncentrosymmetric magnet SrMnSiO were investigated through inelastic neutron scattering measurements. Major magnetic excitations are limite…
Unusual spin dynamics in the van der Waals antiferromagnet FeGa2S4
Yifei Tang, Yoshihiko Umemoto, Yo Kawamoto +5
Spin dynamics in the van der Waals antiferromagnet FeGaS with triangular lattices are investigated using magnetometry, neutron scattering, and muon spin relaxation measurem…
Persistent quantum vibronic dynamics in a double perovskite oxide
Naoya Iwahara, Jian-Rui Soh, Daigorou Hirai +10
Quantum entanglement between the spin, orbital, and lattice degrees of freedom in condensed matter systems can emerge due to an interplay between spin-orbit and vibronic interactio…
