Magnetic properties and microstructure of SmCo5 thin film with perpendicular magnetic anisotropy

Magnetic Thin Films for Perpendicular Magnetic Recording Systems

“…The Ti layer was expected to make smoother the Cu layer deposited upon it, because the melting point and the surface energy of Ti are higher than those of Cu. Indeed, the surface roughness of underlayer for sample C became smaller than that for sample B [42]. The Dq 50 values for samples B and C were 10.1° and 3.1°, respectively.…”

“…The values of H c , SQR, and K u were greater than those of sample A. The enhancement of perpendicular magnetic anisotropy was revealed to be attributable to the suppression of the surface roughness of Cu underlayer [42,43]. The surface roughness was attempted to decrease further by introducing a Ti layer prior to depositing the Cu underlayer.…”

Electroplated Fe films prepared from a deep eutectic solvent

“…In order to obtain the films of those metals, non-aqueous solutions are required, such as molten salts and organic solvents. [8][9][10][11][12][13][14][15][16][17] Recently, Deep Eutectic Solvents (DESs), which are a type of ionic solvents, have been gained much attention, [18][19][20] and are expected as new non-aqueous solutions due to their high conductivity, wide potential window, high purity, and low cost. Some researchers electroplated metallic magnetic materials of Ni, Co, Ni-Co, Ni-Co-Sn, Sm-Co, and Co-Pt from DES-based baths and reported that potentials of DESs as future non-aqueous solutions.…”

Electrodeposition of RE–TM (RE=La, Sm, Gd; TM=Fe, Co, Ni) films and magnetic properties in urea melt

“…Furthermore, it is used to fabricate the permanent magnet materials Sm 2 Fe 17 N x [1][2][3][4]; Gd-Co alloy is known to exhibit perpendicular magnetic anisotropy for magneto-optical recording media [5][6][7][8]; La-Ni alloy is usually used to form hydrogen storing functional material [9][10][11], etc. Up to now, RE-TM films are usually produced by the method of sputtering or melt casting, and the production processes are complex and costly [12][13][14]. Electrodeposition is an alternative method for preparing these films.…”

“…Recently, literature reports have focused on the electrodeposition of RE-TM from high-temperature molten salt [12][13][14][15][16][17], organic solutions [18][19][20] and aqueous solutions [21][22][23]. It is found that the first and second techniques are restricted from application because of its complex equipment, environmental pollution and the higher cost.…”
