Query: New type of stable particle like states in chiral magnets (Chiral
  bobbers)   We present a new type of a thermodynamically stable magnetic state at
interfaces and surfaces of chiral magnets. The state is a soliton solution of
micromagnetic equations localized in all three dimensions near a boundary and
contains a singularity, but nevertheless has a finite energy. Both features
combine to a quasi-particle state for which we expect unusual transport and
dynamical properties. It exhibits high thermal stability and thereby can be
considered as promising object for fundamental research and practical
applications in spintronic devices. We provide arguments that such a state can
be found in different B20-type alloys e.g. Mn$_{1-x}$Fe$_x$Ge,
Mn$_{1-x}$Fe$_x$Si, Fe$_{1-x}$Co$_x$Si.
