Strain-Controlled Magnetic Phase Transitions through Anisotropic Exchange Interactions: A Combined DFT and Monte Carlo Study
Sudip Mandal, Mihir Ranjan Sahoo, Kalpataru Pradhan
Epitaxial strain provides a powerful, non-chemical route to tune the properties of functional materials by manipulating the coupling between spin, charge, and lattice degrees of fr…
Combine effect of site dilution and long-range interaction on magnetic and transport properties in the half-filled Hubbard model
Sudip Mandal, Sourav Chakraborty, Kalpataru Pradhan
We investigate the magnetotransport properties of a diluted half-filled one-band Hubbard model with second-nearest-neighbor hopping on a simple cubic lattice, aiming to explore the…
Exploring the magnetic states in the one-band Hubbard model: Impact of long-range hoppings
Sudip Mandal, Sandip Halder, Kalpataru Pradhan
Correlated electron systems with competing interactions provide a valuable platform for examining exotic magnetic phases. Theoretical models often focus on nearest-neighbor interac…
Microscopic study of interlayer magnetic coupling across the interface in antiferromagnetic bilayers
Sandip Halder, Sudip Mandal, Kalpataru Pradhan
The enhancement of Neel temperature () of low- antiferromagnets in antiferromagnetic bilayers AF1/AF2, where the of AF1 is larger than AF2 (for example enhancemen…
