Antiferromagnetic Skyrmion Crystals in the Rashba Hund's Model on Triangular Lattice
Arnob Mukherjee, Deepak S. Kathyat, Sanjeev Kumar
Motivated by the importance of antiferromagnetic skyrmions as building blocks of next-generation data storage and processing devices, we report theoretical and computational analys…
Antiferromagnetic Skyrmions and Skyrmion Density Wave in Rashba Hund's Insulator
Arnob Mukherjee, Deepak S. Kathyat, Sanjeev Kumar
We discover magnetic phases hosting highly-elusive and technologically important antiferromagnetic skyrmion quasiparicles in a model for Rashba-coupled Hund's insulator. The result…
Rashba-Zener mechanism for nanoscale skyrmions and topological metals
Deepak S. Kathyat, Arnob Mukherjee, Sanjeev Kumar
We report a microscopic electronic mechanism for nanoscale skyrmion formation and topological metalicity. The mechanism, which relies on combining the classic double-exchange (DE)…
New Microscopic Magnetic Hamiltonian for Exotic Spin Textures in Metals
Deepak S. Kathyat, Arnob Mukherjee, Sanjeev Kumar
We derive a new microscopic spin Hamiltonian for Rashba-coupled double exchange metals. The Hamiltonian consists of anisotropic interactions of the Dzyaloshinskii-Moriya (DM) and K…
