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…

Emergent scalar-chirality \& colossal transverse-magnetoresponse in strongly correlated nodal-line half-metal

Jyotirmoy Sau, Sourav Chakraborty, Sourabh Saha +3

Understanding the interplay of strong correlation and temperature in nodal-line semimetals can offer novel ways to control spin currents. Here we consider the 3d-5d double-perovski…

Layer Resolved Magnetotransport Properties in Antiferromagnetic/Paramagnetic Superlattices

Sandip Halder, Sourav Chakraborty, Kalpataru Pradhan

We investigate the layer resolved magnetotransport properties of the antiferromagnetic/paramagnetic superlattices based on one band half-filled Hubbard model in three dimensions. I…

Itinerant ferromagnetism in a spin-fermion model for diluted spin systems

Sourav Chakraborty, Sandip Halder, Kalpataru Pradhan

We investigate the itinerant ferromagnetism using a diluted spin-fermion model, derived from a repulsive Hubbard model, where itinerant fermions are coupled antiferromagnetically t…

Antiferromagnetism beyond classical percolation threshold in the site-diluted half-filled one-band Hubbard model in three dimensions

Sourav Chakraborty, Anamitra Mukherjee, Kalpataru Pradhan

We investigate the impact of site dilution by setting the on-site repulsion strength () to zero at a fraction of sites in the half-filled Hubbard model on a simple cubic lattice…

Impact of Next-Nearest-Neighbor hopping on Ferromagnetism in Diluted Magnetic Semiconductors

Sourav Chakraborty, Subrat K Das, Kalpataru Pradhan

Being a wide band gap system GaMnN attracted considerable interest after the discovery of highest reported ferromagnetic transition temperature 940 K among all diluted…
