Order and disorder in the magnetization of the chiral crystal CrNb3S6

Nanoscale spin solitons in CrNb${}_{3}$S${}_{6}$ are notable for their macroscale coherence, creating an ordered chiral soliton lattice (CSL) that may be tuned by the application of a magnetic field. Through studying experimentally the transitions between the CSL and field-polarized phases, this work shows the existence of a hysteretic disordered phase and reveals the importance of CSL dislocations in mediating the transitions. Gaining control and understanding of dislocations may lead to configurable nanochannels of field-polarized spins, suitable for the propagation of spin waves.
