Summary: | 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. |
