Magnetic and crystal electric field excitations in a spin-orbit coupled frustrated hyperkagome magnet NdLiWO
R. Kolay, S. Guchhait, Indrajeet S. Rathore +4
Rare-earth based garnets provide a viable platform for studying the frustrated driven magnetic properties of the hyperkagome lattices. Herein, we report a comprehensive study of th…
Spin-orbit-entangled frustrated magnetism in fcc Ba(Yb,Nd)NbO double perovskites
S. M. Hossain, Sk. Soyeb Ali, S. Mohanty +7
The search for candidate Kitaev materials has largely focused on 4 and 5 transition-metal compounds with various lattice geometries. In contrast, investigations of rare-earth…

J. J. Abraham, S. Samanta, R. Kolay +5
LaCrSb is a metallic ferromagnet with a layered crystal structure demonstrating intriguing electronic and magnetic properties, such as large anomalous Hall effect, strong can…
Inhomogeneous dynamic state in the double trillium lattice antiferromagnet KBaFe(PO)
S. J. Sebastian, S. S. Islam, R. Kolay +11
The three-dimensional (3D) magnet KBaFe(PO) hosts a double-trillium lattice of Fe (spin, ) ions offering a prototypical platform to study the frustration…
Magnon Spin Current Modulation through Site-Specific Doping in a Compensated Iron Garnet
Anna Merin Francis, P. B. S. Murthykrishnan, Ratnamay Kolay +2
We report on the impact of manganese doping at the iron sites in Gadolinium Iron Garnet (GdIG, GdFeO), employing temperature-dependent spin Seebeck effect and fe…
Spin fluctuations, absence of magnetic order, and crystal electric field studies in the Yb-based triangular lattice antiferromagnet RbYb(VO)
Sebin J. Sebastian, R. Kolay, Abhidev. B +3
We report a comprehensive experimental investigation of the structural, thermodynamic, static, and dynamic properties of a triangular lattice antiferromagnet RbYb(VO).…
