We present a study of the thermal stability of tunneling spin polarization in Al / AlO x /ferromagnet junctions based on the spin-polarized tunneling technique, in which the Zeeman-split superconducting density of states in the Al electrode is used a

We have performed point contact Andreev reflection measurements with a view to study the correlation between measured spin polarization and the interface scattering parameter Z extracted from fits of the modified Blonder-Tinkham-Klapwijk model to the

The origin of the colossal magnetodielectric (CMD) effect in ${\mathrm{DyMn}}_{2}{\mathrm{O}}_{5}$ [N. Hur et al., Phys. Rev. Lett. 93, 107207 (2004)] has been an outstanding question in multiferroics. Here, we report the activation of the electric d

Through a direct observation, based on the spin-polarized tunneling technique, we explore the thermal stability of tunneling spin polarization in Al/Al2O3/Co junctions. Thermal robustness of this parameter, which is of key importance for magnetic tun

Using millimeter wave spectroscopy and numerical simulations we extract the effective parameters of a layered metamaterial made from split ring resonators. In agreement with recent theoretical considerations the effective model for a bulk metamateria
