Journal ArticleDOI
Emission of spin waves by a magnetic multilayer traversed by a current.
TL;DR: In this paper, the interaction between spin waves and itinerant electrons is considerably enhanced in the vicinity of an interface between normal and ferromagnetic layers in metallic thin films, leading to a local increase of the Gilbert damping parameter which characterizes spin dynamics.
Journal ArticleDOI
Side-Jump Mechanism for the Hall Effect of Ferromagnets
TL;DR: In this paper, the main Hall-effect mechanism was shown to be the main mechanism for the dc Hall effect for Fe, Ni, and their alloys above 100 K, while asymmetric scattering dominates below 100 K.
Journal ArticleDOI
Possible existence of a Josephson effect in ferromagnets
TL;DR: The wall moment of a Bloch wall is canted out of the wall plane by an angle, and the Bloch lines are the exact analog of superconducting vortices.
Journal ArticleDOI
Observation of s‐d exchange force between domain walls and electric current in very thin Permalloy films
Paulo P. Freitas,L. Berger +1 more
TL;DR: In this article, large dc current pulses, ≂2 μs long, are sent through 30-40nm-thick Ni87Fe13 films containing Neel walls, and wall displacements are seen for current densities ≥ 1.2×107 A/cm2.
Journal ArticleDOI
Application of the Side-Jump Model to the Hall Effect and Nernst Effect in Ferromagnets
TL;DR: In this paper, a more complete justification of the side-jump model is given, which is used to derive the isothermal Nernst coefficient, where the side jump is assumed to have the same value for spin disorder as for impurity or phonon scattering.
