Laser deposition of SmCo thin film and coating on different substrates

Abstract

Thin films and coatings of permanent magnetic materials are very important for different electronic and micromechanical applications. This paper deals with the fabrication, using pulsed laser deposition (PLD) technique, of good quality magnetic SmCo thin films on polycarbonate, steel, silicon and amorphous quartz substrates, for low cost electronic applications like radio frequency identification (RFID) antennas and electromechanical devices for fuel feeding control in the automotive. X-ray fluorescence and magnetic scanning measurements using giant magneto-resistive (GMR) sensors have been performed to study the functional magnetic properties of the deposited thin films.

Atomic spectrometry update. X-Ray fluorescence spectrometry

“…The study indicated that the thermal stability of Ni-Re-P films was superior to that of Ni-P films. Allocca et al 401 used pulsed laser deposition to form SmCo thin films on polycarbonate, steel, silicon and amorphous substrates for low cost electronic applications such as radio frequency identification antennae and electromechanical devices for fuel feeding control in automotive engines. The films produced on these permanent magnetic materials were analysed by XRF.…”

X-ray Fluorescence Analysis of Waste Sm-Co Magnets: A Rational Approach

“…The possibilities of X-ray techniques for analyzing Sm-Co materials have been described in the literature: X-ray absorption spectroscopy (XAS) [34][35][36], micro X-ray fluorescence (µXRF) [37], energy dispersive X-ray fluorescence (EDXRF) [38][39][40][41][42] and total X-ray fluorescence (TXRF) [43][44][45]. These publications are mainly devoted to the study of the structural features of magnetic materials [43], synthesis, [45][46][47], technological processes [36,42] and thin film analysis [35,36,40], while X-ray fluorescence is used only as a primary characterization.…”

Magneto-optic ellipsometry characterization of Co and SmCo thin films

“…The nominal thicknesses of Au-bottom, Co, Au-top layers are 25nm, 6nm, and 15nm, respectively. A polycrystalline SmCo film (composed of Sm and Co in the ratio 1:1) has been fabricated by a pulsed laser deposition technique on an Si (111) substrate at the chamber pressure 10 -1 Pa and substrate temperature 600K [14]. The nominal film thickness is 8nm.…”
