Geometric influence on the net magnetic moment in LaCoO$_3$ thin films

Autor: Joshi, T., Belanger, D. P., Tan, Y. T., Wen, W., Lederman, D.

The different magnetic behaviors of LaCoO$_3$ films grown on LaAlO$_3$ and SrTiO$_3$ are related to the Co-O-Co bond angles and the constraints imposed on the Co-O bond lengths by the substrate geometries. Long-range magnetic order occurs below T ~ 9

Magnetoelectric properties of 500 nm Cr2O3 films

Autor: Borisov, P., Ashida, T., Nozaki, T., Sahashi, M., Lederman, D.

Publikováno v: Phys. Rev. B 93, 174415 (2016)

The linear magnetoelectric effect was measured in 500 nm Cr2O3 films grown by rf sputtering on Al2O3 substrates between top and bottom thin film Pt electrodes. Magnetoelectric susceptibility was measured directly by applying an AC electric field and

Coherent control of injection currents in high-quality films of Bi2Se3

Autor: Bas, D. A., Vargas-Velez, K., Babakiray, S., Johnson, T. A., Borisov, P., Stanescu, T. D., Lederman, D., Bristow, A. D.

Publikováno v: Appl. Phys. Lett. 106, 041109 (2015)

Films of the topological insulator Bi2Se3 are grown by molecular beam epitaxy with in-situ reflection high-energy electron diffraction. The films are shown to be high-quality by X-ray reflectivity and diffraction and atomic-force microscopy. Quantum

Engineered spatial inversion symmetry breaking in an oxide heterostructure built from isosymmetric room-temperature magnetically ordered components

Autor: Alaria, J., Borisov, P., Dyer, M. S., Manning, T. D., Lepadatu, S., Cain, M. G., Mishina, E. D., Sherstyuk, N. E., Ilyin, N. A., Hadermann, J., Lederman, D., Claridge, J. B., Rosseinsky, M. J.

The oxide heterostructure [(YFeO$_3$)$_5$(LaFeO$_3$)$_5$]$_{40}$, which is magnetically ordered and piezoelectric at room temperature, has been constructed from two weak ferromagnetic AFeO$_3$ perovskites with different A cations using RHEED-monitore

Effects of hydrogen/deuterium absorption on the magnetic properties of Co/Pd multilayers

Autor: Munbodh, K., Perez, F. A., Keenan, C., Zhernenkov, M., Fitzsimmon, M. R., Lederman, D.

The effects of hydrogen (H2) and deuterium (D2) absorption were studied in two Co/Pd multilayers with perpendicular magnetic anisotropy (PMA) using polarized neutron reflectivity (PNR). PNR was measured in an external magnetic field H applied in the

Order Parameter Criticality of the d=3 Random-Field Ising Antiferromagnet Fe(0.85)Zn(0.15)F2

Autor: Ye, F., Zhou, L., Larochelle, S., Lu, L., Belanger, D. P., Greven, M., Lederman, D.

Publikováno v: Phys. Rev. Lett. 89, 157202 (2002)

The critical exponent beta =0.16 +- 0.02 for the random-field Ising model order parameter is determined using extinction-free magnetic x-ray scattering for Fe(0.85)Zn(0.15)F2 in magnetic fields of 10 and 11 T. The observed value is consistent with ot
