Interplay of Spin Waves, Crystal-Field Excitations, and Phonons in Multiferroic Ba3HoRu2O9 revealed by Inelastic Neutron Scattering, Crystal-Field Analysis, and Machine-Learned Phonon Calculations
Ekta Kushwaha, Sayan Ghosh, Gourab Roy +6
Understanding the microscopic origin of spin-dipole coupling and high-energy excitations in correlated 4d-4f multiferroic oxides is challenging because magnetic, crystal-field, and…
Magnetic states of the Kondo lattice CePdSi and their pressure evolution
Yanan Zhang, Zhaoyang Shan, Jiawen Zhang +11
Frustrated Kondo lattices are ideal platforms for exploring unconventional forms of quantum criticality, as well as magnetism and other emergent phases. Here we report the magnetic…
Quantum Griffiths phase in the kagome Kondo lattice CeRhPdSn
Nan Tang, Rajesh Tripathi, Yasuyuki Shimura +3
CeRhSn is a valence fluctuating heavy-fermion metal with a twisted Ce-kagome lattice, displaying zero-field quantum criticality, previously associated with geometrical frustration.…
Signatures of three-state Potts nematicity in spin excitations of the van der Waals antiferromagnet FePSe
Weiliang Yao, Viviane Peçanha Antonio, Devashibhai Adroja +6
In two-dimensional (2D) nearly square-lattice quantum materials, electron correlations can induce an electronic nematic phase with twofold rotational () symmetry that profound…
Crystalline electric field excitations in Weyl semimetal \textit{R}AlSi (\textit{R} = Ce, Pr and Nd)
Lin Yang, Yili Sun, Xiutong Deng +17
The rare earth intermetallic system \textit{R}Al\textit{X} (\textit{R} = rare earth elements, \textit{X} = Si and Ge) is known to be a promising candidate of magnetic Weyl semimeta…
