Co–Pd alloy films for magneto-optical recording

Effect of the bath pH on the electrodeposition of nanocrystalline Pd–Co alloys and their magnetic properties

“…On the other hand, the coercivities obtained are high (H c 41 kOe) and unexpected when compared to the results in the literature [9][10][11]14], where coercivity about 750 Oe or even lower was obtained for this alloy. An explanation for these high coercivites can be the combination of two factors mentioned before: the first one is the Pd-Co lattice strain correlated with the residual stress during the alloy electrodeposition and the second one is the small crystallite size obtained with this process.…”

“…Besides, these alloys also exhibit interesting magnetic properties like the perpendicular magnetic anisotropy and high Kerr rotation angles [9][10][11], two important features required in the magnetooptical recording field. A very peculiar property in relation to this alloy is the fact that small quantities of Co, as little as 0.1 at%, added to Pd, which is paramagnetic, produces a ferromagnetic material [12,13].…”

First order reversal curve analysis of nanocrystalline Pd80Co20 alloy films

“…A variety of techniques have been used over the last decades for the production of PdCo and PtCo alloy films including evaporation, DC magnetron sputtering, molecular beam epitaxy, electrodeposition and e-beam evaporation [1][2][3][4][5][6]. Research efforts have, however, focused mainly on the magnetic properties of Co/Pd multilayer films because of their potential use in high-density perpendicular magnetic recording media [7][8][9][10][11][12].…”

Perpendicular magnetic anisotropy in CoXPd100−X alloys for magnetic tunnel junctions

“…[12,13] CoPd alloys have been investigated in magneto-optics research in the 1990's because of their perpendicular magnetic anisotropy. [14][15][16][17] However, there has been very little exploration of CoPd alloys as pinning layers for pMTJ's. The similar alloy CoPt has also been demonstrated to possess similar perpendicular anisotropy and be utilized in a pMTJ [18][19][20][21][22].…”
