In this paper, the relationship between the initial crystalline behavior and annealing conditions in pulsed laser deposition (PLD)-made Nd-Fe-B and Pr-Fe-B films with rare-earth-rich composition is discussed. The films with rare-earth-rich compositio

In a previous study, the authors developed Nd–Fe–B/glass two-layer films deposited on Si substrates using pulsed laser deposition for micro electro mechanical systems. Here, the fabrication conditions of the films were investigated to determine t

We prepared Fe–Ni films on non-conductive substrates (Polyimide sheets) using the electroless plating method and investigated the metallization process of the PI sheets and the magnetic properties of the films. To obtain suitable conditions for the

Anisotropic Nd-Fe-B film magnets are applied to miniaturized electronic devices and MEMS (Micro Electro Mechanical Systems) devices have been prepared by the sputtering method. However, the thickness of each film is mainly less than 20 μm. We have a

In this research, Fe-Pt thin sheets thicker than 10 microns with Fe contents ranging from 50 to 60 at. % were prepared. Isotropic Fe-Pt thin sheets could be obtained by taking advantage of the exfoliation behavior after depositing Fe-Pt films on Si s

We electroplated Fe-Co films in a citric-acid-based plating bath with saccharin and sodium lauryl sulfate and evaluated the magnetic properties of the films. The Fe content in the film can be readily controlled by the change in the ratio of the Fe re

Although a conventional isotropic Nd-Fe-B bonded magnet (coercivity: 800 kA/m, thickness: 350 μm) has been widely used for a miniaturized motor, deposition of a thick film magnet without resin directly on a small shaft enables us to advance the furt

Abstract Textured ferromagnetic Fe nanowire arrays were electrodeposited using a rectangular-pulsed potential deposition technique into anodized aluminum oxide nanochannels. During the electrodeposition of Fe nanowire arrays at a cathodic potential o

PLD (Pulsed Laser Deposition) method with high laser energy density (LED) above 10 J/cm2 followed by a flash annealing enabled us to obtain isotropic nano-composite thick-film magnets with (BH)max ≧ 80 kJ/m3 on polycrystalline Ta substrates. We als

We have already reported Fe-Ni firms with good soft magnetic properties prepared by using an electroplating method. In our previous studies, we prepared the Fe-Ni films from citric-acid-based baths (CA-baths) and ammonium-chloride-based ones (AC-bath
