  • We study the relationship between long range order parameters and the magnetocrystalline anisotropy of off-stoichiometric D0{sub 22} Mn{sub 2.36}Ga (MnGa) epitaxial films grown on MgO (001) and SrTiO{sub 3} (STO) (001) single crystalline substrates. MnGa films deposited on MgO (001) show rather large irregular variation in magnetization with increasing substrate temperature in spite of the improved long range order of total atomic sites. The specific site long range order of Mn-I site characterized in the [101] orientation revealed the fluctuation of the occupation fraction of two Mn atomic sites with elevated substrate temperature, which appears more relevant to the observedmore » magnetization change than the long range order of the total atomic sites. In case of MnGa films grown on the lattice-matched STO (001), high long range order of the total atomic sites in spite of the existence of secondary phase represents that the lattice mismatch plays a crucial role in determining the atomic arrangement of Mn and Ga atoms in the off-stoichiometric compositional case of MnGa.« less
  • It was demonstrated that Fe-N martensite ({alpha}') films were grown epitaxially on Fe(001) seeded GaAs(001) single crystal wafer by using a facing target sputtering method. X-ray diffraction pattern implies an increasing c lattice constant as the N concentration increases in the films. Partially ordered Fe{sub 16}N{sub 2} films were synthesized after in situ post-annealing the as-sputtered samples with pure Fe{sub 8}N phase. Multiple characterization techniques including XRD, XRR, TEM, and AES were used to determine the sample structure. The saturation magnetization of films with pure Fe{sub 8}N phase measured by VSM was evaluated in the range of 2.0-2.2 T. Themore » post annealed films show systematic and dramatic increase on the saturation magnetization, which possess an average value of 2.6 T. These observations support the existence of giant saturation magnetization in {alpha}''-Fe{sub 16}N{sub 2} phase that is consistent with a recent proposed cluster-atom model and the first principles calculation [N. Ji, X. Q. Liu, and J. P. Wang, New J. Phys. 12 063032 (2010)].« less
  • We report on the fabrication of pseudomorphic wurtzite Ga{sub 1-x}Mn{sub x}N grown on GaN with Mn concentrations up to 10% using molecular beam epitaxy. According to Rutherford backscattering, the Mn ions are mainly at the Ga-substitutional positions, and they are homogeneously distributed according to depth-resolved Auger-electron spectroscopy and secondary-ion mass-spectroscopy measurements. A random Mn distribution is indicated by transmission electron microscopy, and no Mn-rich clusters are present for optimized growth conditions. A linear increase of the c-lattice parameter with increasing Mn concentration is found using x-ray diffraction. The ferromagnetic behavior is confirmed by superconducting quantum-interference measurements showing saturation magnetizations ofmore » up to 150 emu/cm{sup 3}.« less
  • Epitaxial lead titanate (PbTiO{sub 3}) thin films were grown on MgO(100) single-crystal substrate by metal-organic chemical-vapor deposition at a growth temperature of 650{degree}C. The films were dense, stoichiometric, and epitaxial. The domain structure was studied via x-ray-diffraction {omega} scans and in-plane {Phi} scans. Existence of {ital c} and {ital a} domains in the PbTiO{sub 3} films was evident. Consistent with literature reports, the {ital a} domains were found to have four variants 90{degree} apart from each other, tilting about 2.2{degree} away from the surface normal. The population ratio between {ital c} and {ital a} domain of the PbTiO{sub 3} filmsmore » was determined to be approximately 2.3 to 1. The domain structure was found to be stable and reproducible during repeated thermal cycling above and below {ital T}{sub {ital c}}. Furthermore, lattice parameters and Curie temperatures of PbTiO{sub 3} thin films were measured during the thermal cycles. The lattice parameters were found to be smaller and the Curie temperatures were shifted lower than the corresponding bulk values. This is attributed to the film stress effect. A theory based on the Landau{endash}Ginzburg{endash}Devonshire function has been developed to explain the shift of the Curie temperatures. {copyright} {ital 1996 American Institute of Physics.}« less
