MnZn ferrites have been produced via the high-energy ball milling of binary oxide precursors. The milled ferrites have a nonequilibrium cation site distribution, with an unusually high population of Zn cations on the octahedral sites. The particle si

A La0.67Ca0.33MnO3−δ alloy was produced via a low-temperature solid state reaction in a high-energy ball mill. The milled alloy is found to exhibit the paramagnetic-to-ferromagnetic (P–F) transition at 150 K. However, the widely reported insulat

We have grown thin films of (100) oriented La_{0.67}(Ca_{x}Sr_{1-x})_{0.33}MnO_{3} on (100) NdGaO_{3} substrates by off-axis sputtering. We have looked at the changes in the resistivity and magnetoresistance of the samples as the Ca/Sr ratio was vari

Structural inhomogeneities in thin single-crystal films of YBa 2 Cu 3 O 7− δ are characterized using high resolution X-ray diffraction. Results of these measurements show a distribution in the c -axis lattice parameter and variations in the integr

High resolution x-ray diffraction measurements of YBCO single crystals with optimal transport properties reveal gross structural inhomogeneities, such as domains of different oxygen content and high dislocation densities. Thin epitaxial YBCO films sh

The Curie temperature and x-ray photoemission spectra of thin films of La_{0.67}(Ca_{x}Sr_{1-x})_{0.33}MnO_{3} (LCSMO) have been studied as a function of the Ca/Sr ratio. The films were grown by off-axis cosputtering from individual targets of La_{0.
