摘要：

YCo2 and TbCo2 Laves phase compounds were epitaxially grown on (110) W buffer layers by. pulsed laser deposition at a base pressure of 5 x 10(-10) Torr and a substrate temperature of 500 degrees C. The films were characterized in situ by reflection high-energy electron diffraction, and after deposition by grazing-incidence x-ray diffraction and scanning electron microscopy. The relative orientation of the RCo(2)(111), where R = Y or Tb, and the W(110) planes was found to be unlike any previously observed relationship between fee and bcc materials. Two in-plane crystallographic domains of RCo(2)(111) have been pointed out and are discussed in terms of geometrical lattice matching. (C) 1996 American Institute of Physics.
