Myelin Figures-- the Instability of Soap

Myelin figures are long thin cylindrical structures that grow when water is added to the concentrated lamellar phase of certain surfactants such as soap. The Sidney Nagel and Tom Witten groups at the University of Chicago developed a method to produce isolated myelin figures, based on previous investigations of ring stain formation pioneered at the MRSEC. This allowed them to study their growth and stability in detail.

Fabrication of a prototype confined current path, current perpendicular to the plane magnetoresistive device (CCP-CPP GMR) for materials science studies

Schematic of the spin transport device. The large arrows show the configuration of the magnetic electrodes. The small arrows show the electron spins in the semiconductor. The electron spins can be read out using an ordinary voltmeter (V), or with an optical Kerr microscope (shown focusing on the device).

Electrical Detection of Spin Transport in Semiconductors

In semiconductor spintronics, the spin of the electron carries information for both storage and data processing. To some extent, the electron spin can be viewed as a miniature bar magnet that interacts with a magnetic field inside the semiconductor. The orientation of the bar magnet acts as a "bit" of information. Many laboratory demonstrations of spintronics have relied on sophisticated optical techniques for reading out the spin state of electrons.
