A method of fabricating a semiconductor device includes aligning an alignment structure of a wafer to a direction of a magnetic field created by an external electromagnet and depositing a magnetic layer (e.g., NiFe) over the wafer in the presence of the magnetic field and while applying the magnetic field and maintaining a temperature of the wafer below 150&#xb0; C. An insulation layer (e.g., AlN) is deposited on the first magnetic layer. The alignment structure of the wafer is again aligned to the direction of the magnetic field and a second magnetic layer is deposited on the insulation layer, in the presence of the magnetic field and while maintaining the temperature of the wafer below 150&#xb0; C.
