This tutorial article introduces the physics of spin transfer torques in magnetic devices. Our
intention is that it be accessible to beginning graduate students. We provide an elementary …

This paper formulates a general analytic approach to the theory of microwave generation in
magnetic nano-structures driven by spin-polarized current and reviews analytic results …

Spintronics materials have recently been considered for radio-frequency devices such as
oscillators by exploiting the transfer of spin angular momentum between a spin-polarized …

As data transfer rates increase within the magnetic recording industry, improvements in
device performance and reliability crucially depend on the thorough understanding of …

We present experimental and numerical results of current-driven magnetization switching in
magnetic tunnel junctions. The experiments show that, for MgO-based magnetic tunnelling …

The use of spin transfer nano-oscillators (STNOs) to generate microwave signals in
nanoscale devices has aroused tremendous and continuous research interest in recent …

We have directly measured phase locking of spin transfer oscillators to an injected ac
current. The oscillators lock to signals up to several hundred megahertz away from their …

We demonstrate that the lowest threshold of spin-wave excitation in an in-plane magnetized
magnetic nanocontact driven by spin-polarized current is achieved for a nonlinear self …

We use the plane-wave method to determine spin-wave spectra of three-dimensional
magnonic crystals (the magnetic counterpart of photonic crystals) composed of two different …

The operation of an array of coupled oscillators underlying the associative memory function
is demonstrated for various interconnection topologies (cross-connect and star-coupled) …
