The role of local field modes in calculating the effective optical properties of metamaterials
Anderson O. Silva, Ivo T. Leite, José M. Teixeira +3
This letter discusses the importance of the nature of local fields inside a unit cell of optical metamaterials in developing a valid effective medium theory. In particular, we appl…
Quantum effects in atomically perfect specular spin valve structures
J. M. Teixeira, J. Ventura, Yu. G. Pogorelov +1
A simple tight-binding theoretical model is proposed for spin dependent, current-in-plane transport in highly coherent spin valve structures under specularity conditions. Using qua…
Domain imaging, MOKE and magnetoresistance studies of CoFeB films for MRAM applications
J. M. Teixeira, R. F. A. Silva, J. Ventura +7
We present a detailed study on domain imaging, Kerr effect magnetometry (MOKE) and magnetoresistance (MR), for a series of 20 nm CoFeB thin films, both as-…
Short-range effects and magnetization reversal in CoFe thin films: a MOKE magnetometry/domain imaging and AMR study
J. M. Teixeira, R. F. A. Silva, J. Ventura +8
A MOKE magnetometry unit simultaneously sensitive to both in-plane magnetization components, based on an intensity differential detection method, allows us to observe the uniaxial…
