Large Magnetic Anisotropy and Magnetostriction in Thin Films of CoVO
Sangsoo Kim, Christie Thompson, Yan Xin +1
Spinel Cobalt Vanadate CoVO has been grown on (001) SrTiO substrates. Using torque magnetometry experiments, we find that the previously observed temperature induced an…
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…
Raman study of the phonon symmetries in BiFeO single crystals
C. Beekman, A. A. Reijnders, Y. S. Oh +2
In bismuth ferrite (BiFeO3), antiferromagnetic and ferroelectric order coexist at room temperature, making it of particular interest for studying magnetoelectric coupling. The mutu…
The role of stepped surfaces on the magnetotransport in strained thin films of La0.67Ca0.33MnO3
C. Beekman, J. Aarts
We report a comparative study of the properties of very thin films of La0.67Ca0.33MnO3 grown epitaxially under strain on flat SrTiO3 (STO) and on 1 deg miscut STO. For the films on…
Fabrication and Characterization of Topological Insulator BiSe Nanocrystals
S. Y. F. Zhao, C. Beekman, L. J. Sandilands +6
In the recently discovered class of materials known as topological insulators, the presence of strong spin-orbit coupling causes certain topological invariants in the bulk to diffe…
Transport properties of microstructured ultrathin films of La0.67Ca0.33MnO3 on SrTiO3
C. Beekman, I. Komissarov, M. Hesselberth +1
We have investigated the electrical transport properties of 8 nm thick La0.67Ca0.33MnO3 films, sputter-deposited on SrTiO3 (STO), and etched into 5 micrometer-wide bridges by Ar-io…
