Implementation of the magnetic force theorem for large-scale calculations of magnon bands: application to yttrium iron garnet
Thorbjørn Skovhus, Varun Rajeev Pavizhakumari, Thomas Olsen
We present an efficient implementation of the magnetic force theorem which allows for direct evaluation of exchange parameters in q-space. The exchange parameters are calculated di…
Predicting the Néel temperatures in general helimagnetic materials: a comparison between mean field theory, random phase approximation, renormalized spin wave theory and classical Monte Carlo simulations
Varun Rajeev Pavizhakumari, Thomas Olsen
The critical temperature for magnetic order comprises a crucial property of any magnetic material and ranges from a few Kelvin in certain antiferromagnets to 1400 K in ferromagneti…
Bilayer orthogonal ferromagnetism in CrTe-based van der Waals system
Chiara Bigi, Cyriack Jego, Vincent Polewczyk +19
Systems with pronounced spin anisotropy play a pivotal role in advancing magnetization switching and spin-wave generation mechanisms, which are fundamental for spintronic technolog…
Magnetoelectric behavior of breathing kagomé monolayers of from first-principles calculations
John Mangeri, Varun R. Pavizhakumari, Thomas Olsen
We apply density functional theory to explore the magnetoelectric (ME) properties of two-dimensional . These compounds have recently been propose…
