Preparation condition of Co–Pt–Cr–SiO2 films with high coercivity

Influence of the Stress State on $L1_{0}$-FePt Phase Formation within the Fe$_{52}$Pt$_{48}$ Film on Al$_{2}$O$_{3}$ Substrate

“…Фаза L1 0 -FePt має велику енергію магнетокристалічної анізотропії 710 6 Дж/м 3 , високі значення намагнетованості наси-чення ( 1200 емо/см 3 ), коерцитивної сили і високу корозійну стій-кість [1]. Плівки на основі FePt можуть бути термічно стабільними навіть при розмірах зерен, менших за 3 нм, тому дослідженню маг-нетних матеріялів на основі стопу FePt в останні декілька років приділяється значна увага науковців [2][3][4][5][6][7][8][9].…”

Effects of varying CoCrV seed layer deposition pressure on Ru crystallinity in perpendicular magnetic recording media

“…This is larger than the typical values for PMR media and would likely yield poor magnetic performance. [3][4][5] The balance between strain energy and interfacial energy effects demonstrated in the CoCrV system is also likely to occur in other existing systems such as bcc Ta or fcc NiW. 7,27 Deposition of new materials with low Ru͑0002͒ interfacial energies at very low pressures should yield highly crystalline seed layers, which promote the development of Ru͑0002͒ texturing through reduction in interfacial energy.…”

“…1,2 The intermediate Ru layer serves two purposes: first, as an exchange barrier between the soft underlayer ͑SUL͒ and the hard magnetic recording layer and, second, as a crystalline template for the development of texture in the recording layer. Reduction in the c-axis dispersion ͑⌬ 50 ͒ of the Ru layer has been shown to improve the structural and magnetic properties of the recording layer, [3][4][5] therefore significant research has been dedicated to the methods for improving the crystallinity and texture of the Ru layer. Deposition of an additional seed layer such as Ti and Ta between the SUL and the Ru layer is a common technique and has been used to improve the media structure and the resulting performance.…”
