Abstract
A magnetic tunnel junction (MTJ) element is provided. The MTJ element includes a reference layer, a tunnel barrier layer disposed over the reference layer, a free layer disposed over the tunnel barrier layer, and a diffusion barrier layer disposed over the free layer. The MU element in accordance with the present disclosure exhibits a low resistance desired for a low-power write operation, and a high TIM coefficient desired for a low bit-error-rate (BER) read operation.
