We report on the magnetic and transport properties of the antiperovskite GaCMn3 film epitaxially grown on LaAlO3 using the pulsed laser deposition technique. Upon cooling from room temperature, the GaCMn3 film undergoes magnetic transitions from paramagnetic to ferromagnetic to antiferromagnetic. The Curie and Neél temperatures of the film shift to lower and higher temperatures, respectively, by comparison with those of the bulk sample. This discrepancy is mainly ascribed to the compressive strain effect induced by the lattice-mismatch between film and substrate. Negative magnetoresistance, which is about 20% at 0.5 T, is observed near the Neél temperature.

AbstractThe growth, structural and cathodoluminescent (CL) properties of europium activated yttrium oxide (Eu:Y2O3) thin films are reported. The Eu:Y2O3 films were grown in-situ using a pulsed laser deposition technique. Our results show that Eu:Y2O3 films can grow epitaxially on (100) LaAlO3 substrates under optimized deposition parameters. The epitaxial growth of Eu:Y2O3 films on LaAlO3, which has a lattice mismatch of ∼ 60 %, is explained by matching of the atom positions in the lattices of the film and the substrate after a rotation. CL data from these films are consistent with highly crystalline Eu:Y2O3 films with an intense CL emission at 611 nm.

We report second harmonic generation (SHG) from ZnO thin films deposited by the pulsed laser deposition technique at ambient oxygen pressures ranging from 10 mTorr to 1 Torr on glass substrate at room temperature (RT). The dependence of SHG on grain size and thickness of the film is discussed.

ABSTRACTThin films of poly(tetrafluoroethylene) have been deposited on amorphous (7059 Corning Glass) and silicon(l00) substrates at various temperatures by the Pulsed Laser Deposition technique. The deposition was carried out at high vacuum (˜10-6 torr)at temperatures ranging from room temperature to 350°C. The mechanical properties of these films at the varying process temperatures have been evaluated by nano-indentation techniques and compositional properties of the films have been characterized by Fourier Transform Infrared spectroscopy. The deposition parameters have been optimized in order to produce good quality films.

Amorphous films Zr 0.8 Si 0.2 O 2 were deposited on quartz substrates at room temperature, by using pulsed laser deposition technique. After annealing at high temperature, Zr 0.8 Si 0.2 O 2 films suffer a phase separation to precipitate tetragonal ZrO 2 nanocrystals in ZrSiO 4 amorphous matrix. Their crystal structure, microstructure, optical absorbance and photoluminescence have been systematically investigated. Tetragonal ZrO 2 nanocrystals show intense UV emission around 392 nm under photonic excitation with a wavelength of 250 nm. The corresponding models of electronic excitation and transition related to UV emission also have been proposed.
