The present disclosure generally relates to magnetic recording devices with stable magnetization. The magnetic recording device comprises a lower leading shield, an upper leading shield disposed on the lower leading shield, a main pole disposed above the upper leading shield, a trailing shield disposed above the main pole and upper leading shield, and an upper return pole disposed above the trailing shield. A first non-magnetic layer is disposed between the lower leading shield and the upper leading shield, and a second non-magnetic layer is disposed between the trailing shield and the upper return pole. The lower leading shield has a different domain state than the upper leading shield, and the trailing shield and the upper leading shield have a same domain state. The materials and thickness of the first and second non-magnetic layers result in magnetostatic coupling or anti-ferromagnetic coupling.
