Efficient method for magnetic structure exploration based on first-principles calculations: application to MnO and hexagonal ferrites SrFeO

Taro Fukazawa, Haruki Okumura, Tetsuya Fukushima +2

We propose an approach for exploring magnetic structures by using Liechtenstein's method for exchange couplings from the results of first-principles calculations. Our method enable…
