An improved and novel device and fabrication method for a magnetic element, and more particularly a magnetic element (

10

) including a first electrode (

14

), a second electrode (

18

) and a spacer layer (

16

). The first electrode (

14

) and the second electrode (

18

) include ferromagnetic layers (

26

&

28

). A spacer layer (

16

) is located between the ferromagnetic layer (

26

) of the first electrode (

14

) and the ferromagnetic layer (

28

) of the second electrode (

16

) for permitting tunneling current in a direction generally perpendicular to the ferromagnetic layers (

26

&

28

). The device includes insulative veils (

34

) characterized as electrically isolating the first electrode (

14

) and the second electrode (

18

), the insulative veils (

34

) including non-magnetic and insulating dielectric properties. Additionally disclosed is a method of fabricating the magnetic element (

10

) with insulative veils (

34

) that have been transformed from having conductive properties to insulative properties through oxygen plasma ashing techniques.
