This fully custom designed system will provide a platform for growing highly pure samples using Molecular Beam Epitaxy (MBE) and thereafter characterizing them in a ultra high vacuum, low temperature, high magnetic field environment. It is currently being commissioned; imaging and spectroscopy have been achieved at temperatures as low as 50mK.
Along with standard STM capabilities, this system has two unique capabilities: performing time-resolved STM and spin-polarized STM.
STM in the constant current mode provides black and white contour plots of the surface while the addition of spectroscopic information provides an equivalent of color. Our objective is to turn the STM into a high speed camera and provide information about dynamic electronic processes on surfaces. Magnetization dynamics occur through thermal activation, spin tunneling and spin precession [1,2,3]. The characteristic time scales range from eternity (stable magnetization) down to a few hundred picoseconds. Access to such fast behaviour with the STM might appear hopeless when the intrinsic STM dynamic bandwidth is limited to a few tens of kHz due to the high gain of the tunneling current amplifier. Nevertheless, Freeman et. al. from the University of Alberta have developed an experimental scheme based on a pump-probe approach and demonstrated a stunning 25 ps time resolution in the junction mixing mode  . They were using a room temperature air STM, photo-gated pulse generators and micron sized samples made by lithography. While the time resolution was remarkable, they failed to impress the community due to a lack of atomic resolution, the real benchmark of STM. We are currently improving the technique on a home-built STM with atomically clean graphite samples and fully tunable high speed pulse generators. Preliminary results open the door to dynamic spectroscopy and are highly promising for future adaptation in monitoring the dynamics of single molecular magnets.

The recent progress in spin-polarized scanning tunneling microscopy has enabled access to magnetization down at the atomic level . However, only a few groups in the world have succeeded because of non-trivial experimental problems. Therefore, before entering the novel study of molecular magnets, one has to establish the foundation of SP-STM on more conventional systems. With this aim, we studied the thickness dependence of anisotropy for Co thin films on Cu 111  and explored the peculiar properties of an antiferromagnetic Ising lattice with a face-centered cubic symmetry for epitaxial Cr films on Au 100 . Those studies have demonstrated the capabilities of our current apparatus to succeed in this difficult field. Exploration of the magnetic properties of thin films is important because they can also be used as a substrate to host and control the properties of a subsequently deposited molecular magnet. A literature survey shows strong evidence that adaptation of the spin polarized STM technique to molecular magnets is relatively straight-forward [1,2].
