We study nanoscale science, through the use of a scanning probe microscope (SPM). A small cantilever and tip (about 20  nm diamater) is brought close to or in contact with a surface to measure local properties. Topography, magnetism, conductance, and much more can be locally mapped out in this way. There are applications to materials science, device physics, and cell biology, to name just a few.

• enclosed heater stage, heat in inert gas to 250 C
• fluid heater stage, heat in liquid to 80 C
• in-plane magnetic field up to 2500 Oe, using a rare earth magnet
• current preamplifier on the tip holder
