This is a proposal to fund a Scanning Tunnelling Microscope for use under UHV conditions to study the growth of magnetic thin films by molecular beam epitaxy. In MBE growth we are trying to determine the best window in growth rate and temperature to produce epitixial films growing in the layer by layer mode. The in situ STM is useful in providing real space information on the morphology of surfaces and has already been proved by other groups to be a powerful technique in determining the growth mode of a number of metal systems. There are a number of projects in which the relationship between surface morphology, growth and magnetic properties can only be studied by the addition of an STM to our MBE machine. As well as helping us to determine the best growth conditions for the wide variety of systems we will look at two particular problems: (i) The growth of Co on Au: it is known that Co grows as islands 2 atoms high on Au (111) and here we are interested in the magnetic interactions between islands. We will use STM to determine the conditions to control the island size and spacing. (ii) Surfactants are being increasingly used to control metal on metal growth. We have adapted our MBE system to deposit small amounts of low melting point metals as surfactants and the STM will be used to study how these alter the surface morphology. The MBE machine at Leeds is a major facility funded by EPSRC (GR/K07355) which will be greatly enhanced by the addition of an STM and will maintain the machine as a world class facility for studying magnetic films and superlattice.
