The Mean

LaCoO 3 epitaxial films were grown on (100), (110) and (111) oriented LaAlO 3 substrates by the polymer-assisted deposition method. Crystal structure measurement and cross-section observation indicate that all the LaCoO 3 films are epitaxially grown in accordance with the orientation of LaAlO 3 substrates, with biaxial compressive strain in the ab plane. Owing to the different strain directions of CoO 6 octahedron, the mean Co–O bond length increases by different amounts in (100), (110) and (111) oriented films compared with that of bulk LaCoO 3 , and the (100) oriented LaCoO 3 has the largest increase. Photocatalytic degradation of methyl orange indicates that the order of photocatalytic activity of the three oriented films is (100) > (111) > (110). Combined with analysis of electronic nature and band structure for LaCoO 3 films, it is found that the change of the photocatalytic activity is closely related to the crystal field splitting energy of Co 3+ and Co–O binding energy. The increase in the mean Co–O bond length will decrease the crystal field splitting energy of Co 3+ and Co–O binding energy and further reduce the value of band gap energy, thus improving the photocatalytic activity. This may also provide a clue for expanding the visible-light-induced photocatalytic application of LaCoO 3 .

We have extended the low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 600 p.p.m. manganese from magnetic fields of 9 to 56 kG. The crystal field splitting parameters determined at low magnetic fields also characterizes the magnetic anisotropy at high magnetic fields. Manganese–manganese interaction effects are observed in the magnetic anisotropy at manganese concentrations greater than 300 p.p.m. Low temperature magnetic anisotropy measurements on single crystals of zinc containing up to 164 p.p.m. chromium are reported and indicate a crystal field splitting of 0.16 K for the chromium ion.
