Microstructure and Magnetic Properties of Electroless Plated Co‐Ni‐P and Co‐P Thin Films for Magnetic Recording

Abstract: Co‐Ni‐P and Co‐P thin films have been electroless deposited on Al based Ni‐P plated substrates in the pH range 7.8–9.3. The effects of solution pH on nucleation, microstructure, and magnetic properties of these films were investigated by VSM, Auger, and electron microscopy techniques. The magnetic properties are dominated by the microstructure of these films. These two films, deposited at optimum pH, can be used for high density magnetic information storage media.

“…TEM can measure thin films thickness down to several nanometers. The thickness of electroless deposits is usually found by atomic absorption, 14,16 resistance change, 6,13,17 and weight change techniques. 18 Among these methods for measuring the thickness of the films, TEM examination is the most precise.…”

“…The uniform deposition is due not only to the pretreatment but perhaps also to the using of CoNiP instead of the CoP alloy. A difference in the nucleation and growth processes of CoP and CoNiP has been noticed (14). The addition of Ni to the CoP may exert other positive influences: a reduction of the grain size (15); an improvement of the corrosion resistance ( 16); an increase of the magnetocrystalline anisotropy (17) and hence an augmentation of He (15,18) and a reduction of Br.…”

“…Например, с помощью изменения кислотности рабочих растворов можно создавать как высокоанизотропные, так и низкоанизотропные образцы, значительно отличающиеся величиной коэрцитивной силы H C [3]. Благодаря этому химически осажденные кобальтовые пленки обладают большим потенциалом практического использования, например, для создания магнитной памяти [4,5], а также различных управляющих или считывающих устройств [6,7]. Несмотря на то, что в настоящее время существует большое количество работ, посвященных влиянию кислотности раствора на структурные и магнитные свойства химически осажденных кобальтовых пленок [8][9][10][11], к настоящему времени отсутствуют сведения о модификациях кристаллической решетки кобальта в зависимости от размеров составляющих их кристаллитов.…”
