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…
Interfacial-antiferromagnetic-coupling driven magneto-transport properties in ferromagnetic superlattices
Sandip Halder, Subrat K. Das, Kalpataru Pradhan
We explore the role of interfacial antiferromagnetic interaction in coupled soft and hard ferromagnetic layers to ascribe the complex variety of magneto-transport phenomena observe…
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…
