Unit cell orientation of tetragonal-like BiFeO thin films grown on highly miscut LaAlO substrates
C. Beekman, W. Siemons, T. Z. Ward +7
Synchrotron and lab-scale x-ray diffraction shows that tetragonal-like T'-BiFeO3 films on miscut LaAlO3 substrates (miscut < 5 deg) exhibit (00l)-planes tilted away from those of t…
Antiferromagnetic transitions in `T-like' BiFeO3
G. J. MacDougall, H. M. Christen, W. Siemons +5
Recent studies have reported the existence of an epitaxially-stabilized tetragonal-like ('T-like') monoclinic phase in BiFeO3 thin-films with high levels of compressive strain. Whi…
Misfit Strain Accommodation in Epitaxial ABO3 Perovskites: Lattice Rotations and Lattice Modulations
A. Vailionis, H. Boschker, W. Siemons +4
We present a study of the lattice response to the compressive and tensile biaxial stress in La0.67Sr0.33MnO3 (LSMO) and SrRuO3 (SRO) thin films grown on a variety of single crystal…
Determination of the spin-flip time in ferromagnetic SrRuO3 from time-resolved Kerr measurements
C. L. S. Kantner, M. C. Langner, W. Siemons +5
We report time-resolved Kerr effect measurements of magnetization dynamics in ferromagnetic SrRuO3. We observe that the demagnetization time slows substantially at temperatures wit…
Understanding the nature of electronic effective mass in double-doped SrTiO
J. Ravichandran, W. Siemons, M. L. Scullin +5
We present an approach to tune the effective mass in an oxide semiconductor by a double doping mechanism. We demonstrate this in a model oxide system SrLaTiO, w…
Electronic properties of buried hetero-interfaces of LaAlO3 on SrTiO3
Wolter Siemons, Gertjan Koster, Hideki Yamamoto +4
We have made very thin films of LaAlO3 on TiO2 terminated SrTiO3 and have measured the properties of the resulting interface in various ways. Transport measurements show a maximum…
