Title
(EN) MAGNETORESISTANCE ASSEMBLY HAVING A TMR ELEMENT DISPOSED OVER OR UNDER A GMR ELEMENT
(FR) ENSEMBLE DE MAGNÉTORÉSISTANCE COMPRENANT UN ÉLÉMENT TMR DISPOSÉ SUR OU SOUS UN ÉLÉMENT GMR
Abstract
(EN)
A magnetoresistance assembly can include a substrate and a first GMR element disposed over the substrate, the first GMR element having a bottom surface and top surface. The magnetoresistance assembly can further include a first TMR element disposed over the substrate, the first TMR element having a top surface and a bottom surface, wherein a line perpendicular to and intersecting the top or bottom surface of the first TMR element intersects the first GMR element. The first GMR element and the first TMR element are in electrical communication.
(FR)
Un ensemble de magnétorésistance peut comprendre un substrat et un premier élément GMR disposé sur le substrat, le premier élément GMR ayant une surface inférieure et une surface supérieure. L'ensemble à magnétorésistance peut également comprendre un premier élément TMR disposé sur le substrat, le premier élément TMR ayant une surface supérieure et une surface inférieure, une ligne perpendiculaire et sécante à la surface supérieure ou inférieure du premier élément TMR croisant le premier élément GMR. Le premier élément GMR et le premier élément TMR sont en communication électrique.
