Neutron Scattering Studies on Helical Magnetic Orders and their Cross-correlated Phenomena

Abstract

Helical magnetic orders have been extensively investigated for many years by means of neutron scattering. Recent intensive studies on multiferroics and magnetic skyrmions have established a consensus that the helimagnetic orders can induce a variety of emergent phenomena, such as spin-driven ferroelectricity, topological Hall effect, etc. In this article, we briefly review a number of key experiments in this research area, and discuss how we develop the neutron scattering techniques to further investigate the physics related to helimagnetism.
