Helimagnetism and Soliton Lattice in a Chiral Magnet

POSTER

Abstract

Herein, we report the observation of helimagnetism and soliton lattice in a chiral magnet. Below the Curie temperature, the in-plane field-dependent magnetization shows an abrupt increase as well as a narrow hysteresis just before saturation, which indicates a metamagnetic transition from solition lattice to ferromagnetic state. Using Lorenz microscopy, we observed sinusoidal magnetic patterns in real space below the Curie temperature. In thin film samples, we also observed abrupt and hysteretic magnetoresistance jumps when sweeping the magnetic field.
