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…

A new route to enhance the ferromagnetic transition temperature in diluted magnetic semiconductors

Kalpataru Pradhan, Subrat Kumar Das

We investigate the magnetic and the transport properties of diluted magnetic semiconductors using a spin-fermion Monte-Carlo method on a 3D lattice in the intermediate coupling reg…

Electron pairing and evidence of a BCS-BEC crossover in d-wave superconductors

Subrat Kumar Das, Ayan Khan, Saurabh Basu

We have demonstrated that it is possible to access a crossover scenario starting with a weak coupling (BCS) d-wave superconductor to a strongly coupled Bose-Einstein condensate (BE…

The Magnon Spectrum in the Domain Ferromagnetic State of Antisite Disordered Double Perovskites

Subrat Kumar Das, Viveka Nand Singh, Pinaki Majumdar

In their ideal structure, double perovskites like Sr_2FeMoO_6 have alternating Fe and Mo along each cubic axes, and a homogeneous ferromagnetic metallic ground state. Imperfect ann…

Fermionic representation for the ferromagnetic Kondo lattice model -- diagrammatic study of spin-charge coupling effects on magnon excitations

Sudhakar Pandey, Subrat Das, Bhaskar Kamble +4

A purely fermionic representation is introduced for the ferromagnetic Kondo lattice model which allows conventional diagrammatic tools to be employed to study correlation effects.…
