Domain structure of microwires consists of one axial magnetic domain in the
middle of the wire covered by radial domains. Closure domains are at the end of
the wire. Such a structure shows bistable behavior (e.g., the magnetization can
have only two values and ). The switching between the two states runs through
the single Backhouse jump at the field called switching field . This field is
carrier of information about several physical quantities such as external
magnetic field, stress, temperature etc.
