Emergence of Chiral Helimagnetic Order in Chromium-intercalated Tantalum Disulfide CrTa${}_3$S${}_6$ Powders with Controlled Intercalation

Abstract

We report a highly sensitive change in magnetic properties of a chiral Cr-intercalated transition-metal dichalcogenide Cr${}_x$Ta${}_3$S${}_6$. Magnetization curves and small-angle neutron scattering data revealed that the powder samples exhibit chiral helimagnetism with a Cr intercalation quantity $x$ below 0.996, while they show ferromagnetism above 1.000. The emergence and temperature-dependent evolution of the helimagnetic period are argued in terms of sample dimensions of powders and microfabricated crystals.
