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…
