Coexistence of static order and spin dynamics in an S = 5/2 frustrated triangular antiferromagnet
U. Jena, B. Sana, Satish Kumar +6
Frustrated triangular-lattice antiferromagnets in the classical high-spin limit provide a paradigmatic setting in which the interplay of competing exchange interactions, anisotropy…
Nonunitary triplet superconductivity in the Z2 topological metal SrPd2As2
Aarti, Dibyendu Samanta, Kartik Panda +9
In Z2 topological metals, nontrivial band topology and strong spin-orbit coupling (SOC) impose symmetry constraints that can stabilize unconventional superconducting states, even w…
Signature of spin liquid state in a frustrated 3D antiferromagnet
Satish Kumar, U. Jena, A. Bandhopadhay +4
Frustrated pyrochlore lattices in transition-metal oxides provide an ideal platform for realizing exotic quantum states, including spin liquids with unconventional low-energy excit…
Emergent Dynamic Magnetic Ground State in a Mixed 3d/5d Heavy Fermion System CaCu3Ir4O12
J. Ming, Abhisek Bandyopadhyay, G. B. G. Stenning +5
Quantum-disordered magnetic ground states are challenging to identify in three-dimensional (3D) oxides, where strong exchange pathways typically favour long-range magnetic order or…
Magnetic excitation spectrum and hierarchy of magnetic interactions in ErFeO3
Dnyaneshwar R. Bhosale, Piotr Fabrykiewicz, Devashibhai Adroja +3
We report a comprehensive investigation of the excitation spectrum of ErFeO orthoferrite by means of time-of-flight neutron spectroscopy. The spectrum consists of two distinct…
Quasiparticle Dynamics in the 4d-4f Ising-like Double Perovskite Ba2DyRuO6 studied using Neutron Scattering and Machine-Learning Framework
Gourab Roy, Ekta Kushwaha, Mohit Kumar +7
Double perovskites containing 4d--4f interactions provide a platform to study complex magnetic phenomena in correlated systems. Here, we investigate the magnetic ground state and q…
