Homogeneous to multi-scale inhomogeneous complex magnetism in Ba3LnRu2O9 (Ln = Gd, Ho), Revealed by muSR and Machine-Learned Muon-Site Calculations
S. Ghosh, K. Sharma, E. Kushwaha +7
We report a comprehensive muon spin rotation and relaxation (muSR) study of the hexagonal 6H-perovskites Ba3LnRu2O9 (Ln = Gd, Ho) to investigate the role of rare-earth anisotropy i…
Dispersive-phonon-driven room-temperature Ni1+-Ni2+ polaron hopping in spin-charge coupled rutile niobate
Gourab Roy, Mohit Kumar, Sayan Ghosh +4
Understanding how lattice dynamics mediate polaron hopping is essential for designing multifunctional correlated oxides. Here, we demonstrate room-temperature dispersive phonon exc…
Microscopic investigation of spin dynamics in the single-chain magnet Sr4Mn2CoO9
G. Roy, S. Ghosh, M. Kumar +8
One-dimensional single-chain magnets offer a unique platform for studying the interplay of crystal-field effects, exchange interactions, and lattice dynamics. Here, we investigate…
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…
Regulating oxygen content and superconductivity in LaNiO
Peiyue Ma, Jingyuan Li, Xing Huang +17
The synthesis of high-quality Ruddlesden-Popper (RP) nickelates remains challenging due to variations in oxygen content and the prevalence of intergrown RP phases. Precisely contro…
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…
Spin Fluctuations in the Rare-Earth Doped Bilayer Nickelates
Honglin Zhou, Xinman Ye, Gang Wang +7
Spin fluctuations have been generally believed as the pairing glue of high- superconductivity. Recent inelastic neutron scattering (INS) studies have revealed a weak flat spin…
