Graphite as a Highly Correlated Electron Liquid
Although a considerable amount of research work has been done on graphite, its physical properties are still not well understood. In the present...
-
Spin-Transfer Torque and Dynamics
The currents in magnetic multilayers are spin polarized and can carry enough angular momentum that they can cause magnetic reversal and induce stable...

Ferromagnetic Resonance Force Microscopy
The magnetic resonance force microscope (MRFM) is a novel scanning probe instrument that combines the three-dimensional imaging capabilities of...
-
Vortex Dynamics
In this Chapter we will report on progress that has been made in recent years in the investigation of magnetization dynamics in confined magnetic...
