Magnetooptical Kerr Spectra in Sputtered Strontium Ferrite Films

Textured Growth of Strontium Ferrite Thin Films by Sputtering

Crystallographic and Magnetic Characteristics of Ba Ferrite Sputtered Films for High Density Magnetic Recording Disks

Ba ferrite films with non-stoichiometric composition were deposited using Facing Targets Sputtering apparatus. The films with well c-axis orientation and remarkable perpendicular anisotropy were attained even at the substrate temperature below 600°C. Sufficiently large saturation magnetization 4 w o f 3.7 kGand small crystallite size below 20 nm were attained using the targets with Fe-excessive...

Influence of stoichiometry on the dielectric properties of sputtered strontium titanate thin films

The dielectric permittivity, dielectric quality factor ~inverse dielectric loss!, and lattice parameter of 140 nm sputtered SrTiO3 films were dependent on the oxygen partial pressure and total chamber pressure (O21Ar) during film growth. Films were grown at 25 and 75 mTorr ~mT! in an oxygen rich and oxygen deficient sputtering gas environment concurrently on ~100! SrTiO3 and ~111! Pt/~0001! Al2...

Effects of a Pt Underlayer and Interlayer on the Growth Texture of Strontium Ferrite Thin Films

The effects of a Pt underlayer and a Pt interlayer on the textured growth of the sputtered strontium ferrite (SrM) films were investigated. The structural and magnetic properties of SrM films on the Pt underlayers were compared with SrM films on thermally oxidized Si substrates. It was found that much better (00 ) texture was obtained on the films with Pt underlayers, as indicated by the strong...

Ultraviolet detectors in thin sputtered ZnO films.

Sputtering of ZnO is a well-known technique.'9 The application of sputtered thin films of ZnO has mainly been as surface acoustic wave transducers. To our knowledge nobody has yet used these films as detectors for UV radiation. Measurements of the intensity of UV radiation, for example in medical applications in connection with UV irradiation of the skin, are very inaccurate due to the lack of ...
