16. S. Zhang, P. M. Levy, A. C. Marley, and S. S. P. Parkin [Phys. Rev. Lett. 79, 3744 (1997)] have assumed that surface magnons are excited, and did not consider phonons and bias dependence of direct tunneling. The present fit indicates that the bulk, rather than the surface, magnons result in observed bias behavior of the TMR.
