(author), Khokhlov, V.A. (author)Microstructure and magnetic properties of BiMnO3 and BiFe0.5Mn0.5O3 films, prepared by rf magnetron sputtering on LaAlO3 (001) single-crystalline substrate, are investigated. The selected-area electron diffraction analysis allows us to identify the crystal structure of the BiMnO3 film as orthorhombic, while the BiFe0.5Mn0.5O3 film has a...journal article 2012

Khalili Amiri, P. (author), Zhuang, Y. (author), Schellevis, H. (author), Rejaei, B. (author), Vroubel, M. (author), Ma, Y. (author), Burghartz, J.N. (author)This work presents a series of high-resistivity nanogranular Co–Al–O films with maximum resistivity of ? 110?m??cm. The films were deposited using pulsed dc reactive sputtering of a Co72Al28 target in an oxygen/argon ambient. The samples were characterized by scanning electron microscopy (SEM), M-H loop measurements, and s-parameter measurements...journal article 2007

Yang, Z.Q. (author), Zhang, Y.Q. (author), Aarts, J. (author), Wu, M.Y. (author), Zandbergen, H.W. (author)We report the effects of biaxial strain on the charge ordering temperature Tco of the mixed-valent manganite perovskite oxide Pr0.5Ca0.5MnO3. Thin films were grown on SrTiO3, which has a 1.3% larger in-plane lattice parameter. Other substrates were used for comparison. Transport measurements combined with data from electron microscopy show that...journal article 2006

Zhuang, Y. (author), Vroubel, M. (author), Rejaei, B. (author), Burghartz, J.N. (author), Attenborough, K. (author)A granular NiFe thin film with large in-plane magnetic anisotropy and high ferromagnetic-resonance frequency developed for radio-frequency integrated circuit (IC) applications is presented. During the deposition, three-dimensional (3D) growth occurs, yielding NiFe grains (? ? 1.0??m). Nanonuclei (? ? 30–50?nm) are observed in single NiFe grains...journal article 2005
