Magnetic phase transitions in the chiral helimagnet Cr$_{1/3}$NbS$_2$

Cr$_{1/3}$NbS$_{2}$ is a long period chiral helimagnet crystallizing in the noncentrosymmetric, hexagonal~space group P6$_3$22. Helimagnetic ordering along the c-axis is attributed to the competition between the symmetric exchange interaction, favoring parallel moments, and the anti-symmetric Dzyaloshinsky-Moriya interaction, favoring perpendicular moments. Recently, the ground state helical ordering is found to be destabilized by a magnetic field applied perpendicular to c, forming a chiral soliton lattice phase, and, above a critical field, a commensurate ferromagnetic state. Thermal and transport properties also show interesting behaviors in the vicinity of the transition temperature. Here we present magnetic, thermal and transport properties of Cr$_{1/3}$NbS$_{2}$ measured on single crystals, along with recent results from neutron scattering experiments conducted on the four circle single crystal diffractometer and general purpose SANS at the High Flux Isotope Reactor, ORNL.
