these samples were prepared by sputtering directly onto nacl crystals dissolving away the crystal in milli q water and then floating the alloy coating onto an uncoated copper tem grid the samples included the use of the additional hcp transition metal ti plus the bcc transition metals mo and w which were investigated for comparative purposes the diffraction pattern from each sample was analysed in order to determine the lattice parameter a 0 in the case of crystalline coatings or simply to confirm an amorphous structure when no crystalline material is observed the experimental window for the dopant target power was chosen based on the overall maximum bayer ratio achieved for each dopant material this window was in the range of 50 to 100 w the resulting powers tested for the different alloy mixtures were mo and w 100 w and co ti and zr 50 w the dominant phase present for the solid solutions of these samples was found to be the bcc structure however for certain samples additional phases were observed the diffraction spectra of crco x crzr x and crti x showed the presence of a secondary phase different from bcc as indicated by the arrows in fig5 this secondary phase was identified as a u03c9 hcp phase a displacive phase transformation from the bcc phase further to this analysis it was noted that amorphous material is present in the background of the diffraction patterns with this phase being most noticeable for the crti x alloy.
