Orbital Hall effect-driven spin-orbit torque enhancement in Ti-based systems via rare-earth interface engineering
Rohiteswar Mondal, Chennoju Raghu, Animesh Baral +2
Orbital currents in light metals offer large orbital Hall conductivities, yet translating this into practical spin-orbit torque efficiency is hindered by fundamental limitations. I…
Exchange Interaction in Binuclear Complexes with Rare Earth and Copper Ions: A Many-Body Model Study
Indranil Rudra, C. Raghu, S. Ramasesha
We have used a many-body model Hamiltonian to study the nature of the magnetic ground state of hetero-binuclear complexes involving rare-earth and copper ions. We have taken into a…
Structural and Electronic Instabilities in Polyacenes: Density Matrix Renormalization Group Study of a Long--Range Interacting Model
C. Raghu, Y. Anusooya Pati, S. Ramasesha
We have carried out Density Matrix Renormalization Group (DMRG) calculations on the ground state of long polyacene oligomers within a Pariser-Parr-Pople (PPP) Hamiltonian. The PPP…
Properties of low-lying states in some high-nuclearity Mn, Fe and V clusters: Exact studies of Heisenberg models
C. Raghu, Indranil Rudra, Diptiman Sen +1
Using an efficient numerical scheme that exploits spatial symmetries and spin parity, we have obtained the exact low-lying eigenstates of exchange Hamiltonians for the high nuclear…
Evaluation of low-energy effective Hamiltonian techniques for coupled spin triangles
C. Raghu, Indranil Rudra, S. Ramasesha +1
Motivated by recent work on Heisenberg antiferromagnetic spin systems on various lattices made up of triangles, we examine the low-energy properties of a chain of antiferromagnetic…
