Influence of Ni content on the microstructure and magnetic and magneto-optical properties of sputtered (Co1-xNix)Pt3 alloy films

Electrodeposition of CoNi and CoNiP alloys in sulphamate electrolytes

“…In particular, the use of cobalt-nickel system has been extended to some magnetic applications, especially in microsystems technology for manufacture of sensors, actuators or inductors [5][6][7], and their use has been tested as magneto-optic memory material as very desirable data storage material [8,9]. Cobalt and nickel form a solid solution fact that possibilities "to tailor" the alloy composition.…”

Alloy formation of Co/Ni/Pt(111)

“…Crangle et al reported that the Curie temperature of Co-Pt alloy decreases with the increase of Pt content, it decreases more rapidly in the CoPt 3 region [21]. The decrease of Curie temperature is affected by the composition of the alloy film [22]. From the calculation of Ni% and Co% (not shown here), we found that the ratio of Ni% to Co% keeps constant ($0.34) when the annealing temperature is between 750 K and 850 K, meanwhile the Pt% increases almost linearly with the annealing temperature.…”

Effects of High Magnetic Field Postannealing on Microstructure and Properties of Pulse Electrodeposited Co-Ni-P Films

“…Recently, there have been a number of investigations on the perpendicular magnetic anisotropy of Co-Ni-P films for high density recording. On the other side, Co-Ni-P alloy, with a special composition ratio, is a prospective hard magnetic material for microelectromechanical systems (MEMS) application [4,5] and perpendicular magnetic recording media [6,7], because of its relatively high magnetic saturation ( ) and coercivity ( ). Electrodeposition Co-Ni-P alloy films have many advantages over electroless deposition and vacuum processes: easy maintenance, low temperatures, and the ability to control microstructure and properties.…”
