A magnetic structure for use in a magnetic recording head, the structure having improved resistance to stray field writing. The magnetic structure can be for example a magnetic shield or a return pole of a perpendicular write element. The structure includes a main body portion which may have a generally rectangular configuration, and first and second wing portions extending laterally from the sides of the body at or near the ABS. The wing portions have a depth measured perpendicular to the ABS that is significantly less than the depth of the body portion (preferably less than 25 percent of the body portion). The wing portions may also have notches formed in their ABS edges. The wings conduct flux from the ABS edge of the body portion and create a flux choking effect for magnetic flux flowing into the wings.
