TL;DR: In this article, a composite medium consisting of insulating magnetodielectric spherical particles embedded in a background matrix is studied and it is shown that the effective permeability and permittivity of the mixture can be simultaneously negative for wavelengths where the spherical inclusions are resonant and that the medium results in an effective "double negative" media.

TL;DR: In this paper, an approximate nonlinear theory of microwave generation by spin-polarized direct current in a magnetic nanocontact magnetized in an arbitrary direction was presented.

TL;DR: In this article, the magnetization dynamics of soft ferromagnetic thin films can be tuned using rare-earth (RE) dopants, and low concentrations of Tb in 50 nm Ni/sub 81/Fe/sub 19/ films are found to increase the Gilbert magnetic damping parameter /spl alpha/ over two orders of magnitude without great effect on easy axis coercivity or saturation magnetization.

TL;DR: The electrical response of an individual multiwalled carbon nanotube and its contacts, welded to a coplanar waveguide (CPW), was measured up to 24 GHz using a technique that removes environment effects.

TL;DR: In this paper, the authors demonstrate a method of eliminating overshoot and ringing in magnetization dynamics when the system bandwidth includes the intrinsic ferromagnetic resonance (FMR) and employ staggered step excitation for the cancellation of FMR oscillations while maximizing the magnetization response.
