Products Description
Cobalt Tantalum Zirconium (CoTaZr) Alloy Target is produced by melting technology, it's usually applied for magnetic data storage field. With up to 3N5 purity, uniform grain size, lower oxygen content, end user can obtain constant erosion rates as well as high purity and homogeneous thin film coating during PVD process.
Cobalt Tantalum Zirconium (CoTaZr) Alloy Target is one of the sputtering targets used in the vacuum coating industry. It is a product obtained by high-purity cobalt, niobium and zirconium through high-vacuum melting to obtain a cast billet, and then processed. It has a specific size and shape of high-purity cobalt-niobium-zirconium material, which is installed on a vacuum coating machine and sputtered into a film.
The nanocrystalline magnetic film obtained by sputtering the CoNbZr alloy target and the polycrystalline film are mainly three kinds of magnetic films: cobalt Co, cobalt-iron CoFe and permalloy NiFe. The non-magnetic isolation layer is a sandwich film layer formed by precious metal materials such as copper Cu. It has an extremely thin overall thickness (about 10nm), a large magnetoresistance effect (more than 10%), a stable single domain state, excellent reversal characteristics, and a reversal field uniformity deviation of <8%. It is an important film material for the production of RAM, MRAM and other storage devices.
