Abstract:

We present how macroscopically coherent ordering within a chiral state can be manifested in the physical properties within the context of an archetypical system-the chiral spin soliton lattice in a monoaxial chiral magnet CrNb3S6. Using magnetotransport measurements and state-of-the-art Lorentz electron microscopy, we demonstrate spin soliton confinement in 1-mu m-wide grains with different crystalline chirality and discretized magnetoresistance in 10-mu m-wide crystals. Discretization effects are found to be prominent when the system size is reduced to the order of 10 mu m along the chiral axis. A consequence that we identify is a robust coherence of the chiral soliton lattice against deformation. The spin configuration at the grain boundaries, which leads to soliton confinement, is experimentally clarified.
