One of the current frontiers in magnetism is to understand the domain structure and the magnetization reversal
in nanometer sized particles. Explorations at these length scales have been aided by the development of new
magnetic imaging techniques [1] one of which is the magnetic force microscope (MFM), a variant of the atomic
force microscope. We have utilized the high resolution MFM (30 nm) we developed [2] to increase our
fundamental understanding of magnetism on this length scale. We will discuss the magnetic reversal of chains

FEI, Hillsboro is hosting a a day of exploration for OSU Physics grad and undergrad students by opening up its lab. The visit will provide insights into the possibilities for a career in physics, but it is not a recruiting function. Lunch and refreshments will be provided.

The plan is to introduce FEI to the group, provide presentations on the technology and how people with physics backgrounds contribute to FEI's business. Following that will be an

A microscopic understanding of the Ferromagnetic/Antiferromagnetic (F/AF) direct exchange coupling
or exchange biasing has been elusive for the over 45 years since its was discovered. In part, the almost
exclusive use of hysteresis loops to study the phenomenon has limited our understanding. A new experimental
technique was developed to study the exchange coupling between a ferromagnet and antiferromagnet [Appl.
Phys. Lett. 69,3932-3931 (1996)]. This new technique has enjoyed considerable success in explaining many
