“…There are various candidates for the perpendicular recording materials such as Co-Cr thin films [2] , Fe and Co plated films on aluminum oxide substrate [3], and Ba-ferrite particulates [ 4]. The Co-Cr thin films have been most intensively studied because of an excellent crystallographic characteristics and magnetic properties.…”

Abstract---Pb added Ba-ferrite films were prepared at the substrate temperature of 550 CC by dc magnetron sputtering and their crystallographic characteristics and magnetic properties were investigated. The addition of Pb facilitates the crystallization and improves the crystallinity for hexagonal M phase. The films prepared in this study exhibit a good c-axis orientation and the c-axis dispersion angle L1 (lso is as small as 1°. The coercivities Hc.L and Hc H and Ms of the films are 1.0 kOe, 0.2 kOe and 240 emu/cc, respectively.

“…In 1975, using an anodic oxide coating film on aluminum, magnetic properties of electrodeposited Co nanowires and Co-Ni alloy nanowires were investigated (Kawai & Ueda, 1975). In 1986, as an application to perpendicular magnetic recording medium, alumite films containing Fe nanowires were fabricated (Tsuya et al, 1986). In 1988, magnetization curling process in perpendicular direction was studied using Fe nanowire arrays in alumite media (Huysmans et al, 1988).…”

Abstract.To synthesize an array of numerous ferromagnetic nanowires, iron-group metals such as Ni, Co, Fe, Ni-Fe and Co-Fe alloys were electrodeposited from aqueous solution into a nanoporous template with numerical cylindrical nanochannels . The shape of nanowires was precisely transferred from the nanochannel template and the aspect ratio reached to around 150. Magnetic hysteresis loops revealed that Ni, Co and Fe nanowires were spontaneously magnetized to the long axis direction. Coercive force of the nanowires with 6000 nm in length was increased in decreasing the pore-diameter. The coercive force of Co nanowires with 40 nm in diameter has increased up to 1084 Oe.
