Current Density and Thickness Effects on Magnetic Properties of Electrodeposited CoPt Magnetic Films

Abstract

The dominant magnetization reversal behavior of electrodeposited CoPt samples with various thicknesses deposited at different current densities was the domain wall motion by means of wall pinning. The magnetic interaction mechanism was dipolar interaction for all samples. The dipolar interaction strength was significantly affected by the sample thickness rather than by the current density, while the magnetic properties were closely related to the current density.

Magnetic Properties of Electrodeposited Cobalt-Platinum (CoPt) and Cobalt-Platinum-Phosphide (CoPtP) Thin Films

“…Kim et al also investigated magnetic properties (e.g., coercivity, magnetic moment etc.) to film thickness (Kim et al, 2013). Guillamat et al electrodeposited CoPt thin film from deep eutectic solvent (Guillamat et al, 2012) whereas Hnida et al electrodeposited nanowires using template directed method (Hnida et al, 2016).…”

Magnetic and magnetoresistance of BiFe0.5Cr0.5O3 thin film over Pt(111) substrate at various thicknesses by sol‐gel method

“…Therefore, the magnetic individuality is greatly affected by film deposition, current density, sample thickness, electrolyte concentration, etc . As a result, the growth rate and sample thickness must be known to understand the magnetic properties like grain size, surface roughness, packing fraction, and crystalinity . High magnetization, low coercivity with a large magnetic/insulator thickness ratio is mostly preferred to achieve high effective permeability in multilayer core.…”

The purpose of this work is to find the relation of deposition parameters, and the structural and magnetic properties of BFCO deposited over the Pt(111)oriented substrate.…”

Composition Gradient in Electrodeposition of Thin CoPt Films from the Quiescent Hexachloroplatinate Solutions

“…The electrodeposition of CoPt alloys has been studied intensively as a possible method for fabrication of BPM and MEMS devices. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] The effects of thickness or deposition time have been addressed in several papers. 8,9,14,15 It was found that magnetic properties such as: coercivity, perpendicular anisotropy, squareness, and magnetization are thickness dependent.…”

Similar magnetic variations were also found as a function of current density.…”
