Pressure-induced Frustration of Magnetic Coupling in Elemental Europium
Shu-Ting Pi, Sergey Y. Savrasov, Warren E. Pickett
Applying linear response and the magnetic force theorem in correlated density functional theory, the inter-sublattice exchange constants of antiferromagnetic Eu are calculated and…
Anisotropic Multipolar Exchange Interactions in Systems with Strong Spin-Orbit Coupling
Shu-Ting Pi, Ravindra Nanguneri, Sergey Savrasov
We introduce a theoretical framework for computaions of anisotropic multipolar exchange interactions found in many spin--orbit coupled magnetic systems and propose a method to extr…
Calculation of Multipolar Exchange Interactions in Spin-Orbital Coupled Systems
Shu-Ting Pi, Ravindra Nanguneri, Sergey Savrasov
A new method of computing multipolar exchange interaction in spin-orbit coupled systems is developed using multipolar tensor expansion of the density matrix in LDA+U electronic str…
