The quantum corrections are calculated to the energy of the soliton in the easy‐plane ferromagnetic spin chain with two anisotropies. A semiclassical continuum approximation is used which allows to treat the leading order deviations from idealized classical behavior. The soliton density at finite temperatures is also calculated.
