The market for thin films of complex oxides obtained by different deposition techniques is increasing exponentially in last decades due to large variety of possible application such as high-efficient solar cell, optoelectronic devices, etc. pulsed laser deposition (PLD) is a versatile growth technique and recently became more attractive for industrial applications due to the possibility to obtain crystalline thin films on a large area. Laser processing techniques were successfully used to obtain thin films with good optical properties starting from simple oxides, such as Sm 2 O 3 , ZrO 2 , etc., to more complex lead-free materials: Sr x Ba 1Àx Nb 2 O 6 (SBN) and Na 1/2 Bi 1/2 TiO 3À x%BaTiO 3 , or superconductive oxide YBa 2 Cu 3 O 7Àδ . When oxide thin films are designated for electronic and optoelectronic devices or for solar cells, the optical properties and the thickness must be well known. For this purpose, the spectroscopic ellipsometry technique was developed. Ellipsometry is a powerful technique to determine the optical properties of thin films especially when the thicknesses of thin films are in a nanometer range.

“…We have also studied thick-film magnets for Nd-Fe-B, Sm-Co, and Fe-Pt alloys prepared by Pulsed Laser Deposition (PLD) or vacuum arc deposition methods, which have high deposition rates (>several lm/h). [1][2][3][4] For applying the thick-film magnets into commercial small-size devices, high economic viabilities, such as high deposition rate and simplicity of fabrication equipment, are required. Therefore, chemical processes such as electroplating methods are preferred over physical processes such as sputtering, PLD, and arc deposition methods.…”

Fe-Pt thick-films were electroplated on Ta substrates using a direct current, and the magnetic properties of the film were evaluated. The Fe-Pt films with the thickness from 3 to 23 lm were obtained by changing in the plating time from 2 to 20 min. As the as-plated Fe-Pt films had the disordered fcc (face-centered-cubic) structure and low coercivity (<5 kA/m), we annealed the films at 700 C for 60 min. The annealing induced the phase transformation from fcc structure to fct (face-centeredtetragonal) one, and we consequently obtained the Fe 50 Pt 50 thick-films with large coercivity of approximately 700 kA/m. The large coercivity was observed in the wide thickness range for our experimental conditions. Therefore, we concluded that our prepared Fe-Pt film is one of the attractive thick-film magnets.
