Nd–Fe–B films and microstructures

Abstract

Nd-Fe-B films have been reviewed earlier by Herbst39 and Cadieu.40 Reviews on Nd-Fe-B mater-The fabrication methods of Nd-Fe-B thin and thick ials have been published by Cadieu,41 Buschow films, methods for structuring films, and methods of making Nd-Fe-B microparts are reviewed.

Texture and magnetic properties of hard magnetic RE–Fe–B thin films deposited on a Nb buffer layer

“…Of special interest are c-axis oriented films [1,2] for which it is possible to obtain both high remanence J r and high intrinsic coercivity i H c with consequently large magnetic energy product (BH) max . It is necessary to have a columnar grain structure in order to obtain highly textured films.…”

Thin films of NdFeB deposited by PLD technique

“…With conventional media, this so-called superparamagnetic limit is expected to be reached very soon, and in order to reduce sizes further and to exceed densities of 100 Gbit/in. 2 , materials having a higher magnetic anisotropy are needed [4][5][6][7].…”

Effective anisotropy field in anisotropic nanostructured ferromagnetic materials

“…Recently, various deposition techniques such as sputtering and pulsed laser deposition have been applied to fabricate the nanocrystalline ferromagnetic thin films such as Nd-Fe-B [14,15] and Sm-Co [16] thin films for hard magnets, CoPt and FePt thin films [17,18] for high-density recording media. Moreover, ferromagnetic nanowires [19] and nanoparticles [20,21] have been prepared by electric chemical deposition and arc-discharge.…”
