Long-range magnetic interactions in Nd${}_2$PdSi${}_3$ and the formation of skyrmion phases in centrosymmetric metals

Viviane Peçanha-Antonio, Zhaoyang Shan, Michael Smidman +11

We present an extensive X-ray and neutron scattering study of the structure and magnetic excitations of Nd${}_2$PdSi${}_3$, a sister compound of Gd${}_2$PdSi${}_3$ which was recently found…
