    Abstract: A method of making an MgO barrier layer for a TMR sensor, the method including depositing a first Mg layer in a first chamber, depositing a second Mg layer on the first Mg layer using a reactive oxide deposition process in the presence of oxygen in the first chamber or in a second chamber different than the first chamber, depositing a third Mg layer on the second MgO layer in either the first chamber, the second chamber, or a third chamber, and annealing the first layer, the second layer, and the third layer to form an MgO barrier layer.
