Abstract

Over the past year a vacuum chamber for elevated and cryogenic temperature infrared reflectance spectroscopy was built and tested. This involved design and construction of many complex pieces of equipment which have been tested as well. The vacuum chamber has been tested and successfully holds pressures below 1x10-7mbar. The temperature range has been tested for 400K to 5K. Sample positioning has been controlled to within 10 micron. This new equipment has been used to find the optical properties of various materials, for example La1-xSrxMnO3 thin films on LaAlO3. At cryogenic temperatures the gap structure of the incommensurate spin density wave ground state of chromium has been investigated.
