title = "Intrinsic hysteresis due to the surface barrier for chiral solitons in monoaxial chiral helimagnets",
abstract = "We present a theory of a surface barrier for isolated solitons to enter chiral magnets, in an analogous way to that of the Bean-Livingston barrier in the type II superconductors. With this theory, we discuss hysteresis observed in magnetoresistance (MR) measurements of monoaxial chiral helimagnet CrNb3S6. We argue that a large jump in the decreasing field process of MR of micrometer-sized samples is due to the disappearance of the surface barrier for the chiral soliton at a field H=Hb. This argument is justified through agreement between the experimental results at 10 K and our theoretical result Hb/Hc=4/π2∼0.4 (with thermodynamic critical field Hc) based on the sine-Gordon model.",
