Spin-polarized Scanning Electron Microscopy
Proceedings, annual meeting, Electron Microscopy Society of America, 1990 Spin-polarized scanning electron microscopy (spin SEM), where the secondary electron spin polarization is used as the image signal, is a novel technique for magnetic domain observation. Since its first development by Koike and Hayakawa in 1984, several laboratories have extensively studied this technique and have greatly improved its capability for ...

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides
Advanced Functional Materials, EarlyView.A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...

Demo 24-07 Polarization by Scattering
, 2001 Light is polarized when it scatters from materials like air or water. This demonstration shows some of the properties of this polarization, using the apparatus of Figure 1, in which the light beam passes through a water tank into which a small amount ...

Ultrafast circular polarization oscillations in spin-polarized vertical-cavity surface-emitting laser devices [PDF]
, 2010 Spin-polarized lasers offer new encouraging possibilities for future devices. We investigate the polarization dynamics of electrically pumped vertical-cavity surface-emitting lasers after additional spin injection at room temperature.

Polarization: Concepts, Measurement, Estimation [PDF]
The purpose of this paper is two-fold. First, we develop the measurement theory of polarization for the case in which asset distributions can be described using density functions.

Generation and characterization of polarization scrambled optical signals [PDF]
, 2012 Controlling the state of polarization of a light beam of an optical fiber is of crucial importance. Non-Linear Polarization Pulling (NLPP) is an all-optical way to control the state of polarization of signals which has been proposed in recent years ...
