Spatial, momentum and energy separation of electronic spins in condensed-matter systems
guides the development of new devices in which spin-polarized current is generated and …

The vision of using light to manipulate electronic and spin excitations in materials on their
fundamental time and length scales requires new approaches in experiment and theory to …

The Fermi surface plays an important role in controlling the electronic, transport and
thermodynamic properties of materials. As the Fermi surface consists of closed contours in …

We report magnetic and electrical measurements of Nb Josephson junctions with strongly
ferromagnetic barriers of Co, Ni, and Ni 80 Fe 20 (Py). All these materials show multiple …

We report on experimental studies of superconductor-ferromagnet layered structures. Strong
oscillations of the critical supercurrent were observed with the thickness variation of the …

We investigated the spin pum** dam** contributed by paramagnetic layers (Pd, Pt) in
both direct and indirect contact with ferromagnetic Ni 81 Fe 19 films. We find a nearly linear …

We have measured the superconducting transition temperature T c of Ni/Nb/Ni trilayers
when the magnetizations of the two outer Ni layers are parallel (P) and antiparallel (AP). The …

We study the efficiencies of dam**like and fieldlike torques in Nb/Ni and Ta/Ni bilayers
and compare them with Nb/Ni 81 Fe 19 (Py) and Ta/Py as a function of the thickness of a …

We demonstrate a strong dependence of the effective dam** on the nanomagnet size and
the particular spin-wave mode that can be explained by the theory of intralayer transverse …

We present measurements of thermal and electrical conductivity of polycrystalline permalloy
(Ni-Fe), aluminum, copper, cobalt, and nickel thin films with thickness< 200 nm. A …
