A magnetic structure includes a first portion and a plurality of second portions. The first portion extends in a first direction. The plurality of second portions extend from ends of the first portion in a second direction. The first and second directions are perpendicular to one another. Two magnetic domains magnetized in directions opposite to each other and a magnetic domain wall between the magnetic domains are formed in the magnetic structure.
