We have fabricated multiple MgO magnetic tunnel junctions (MTJ) with 1.7 nm oxide, which are connected in series, and layed out in a serpentine geometry. We performed DC tunnel magnetoresistance measurements and AC impedance spectroscopy with crossed DC magnetic fields in the easy and hard axis directions. A simple RLC circuit model is used to fit our data… CONTINUE READING
