The University of Maryland MRSEC grants ended in September 2013 after 17 years of successful operation. This site remains as a history of the center, but will not be actively maintained.

What is our logo?
Our MRSEC logo shows the arrangement of atoms at the surface of a crystal. Crystals are made up of layers, or "planes" of atoms, perfectly stacked in an ordered pattern. Because this surface has been cut at a slight angle to the crystal planes, it appears "stepped" (we call this type of surface a vicinal surface). Modern scanned-probe microscopes, such as the STM, allow us to see the atoms at the surface of a crystal, producing images very similar to this one.

Floating Zone Furnace

Overview:

Our floating zone furnace (Crystal Systems Inc.Model FZ-T-12000-X-S) employs four halogen optical lamps to achieve crystal growth temperatures up 2100ºC at pressures of 10^-8 - 10 bar and is particularly suited to the growth of oxide single crystals. It permits growth of both congruent and incongruent melting systems. This system is utilized to prepare crystals with high spin polarization, as well as ferroelectric materials.
