Magnetic Recording Material is Magnetic material that use Magnetic properties and Magnetic effects to input , record, store, and output information, such as sounds, images, figures, etc. It is divided into magnetic recording medium material and magnetic head material.The former mainly completes the information recording and storage function, and the latter mainly completes the information writing and reading function.In physics, these products are called magnetic recording media (only magnetic powder is considered magnetic recording materials).
In the consumption structure of these products, audio tapes account for the largest proportion. Magnetic recording has the characteristics of high recording density, stable and reliable, repeatable use, variable time reference, wide frequency range, fast information writing and reading.Widely used in broadcasting, film, television, education, medical treatment, automatic control, geological exploration, electronic computing technology, military, aerospace and daily life.
Magnetic recording materials are classified into granular materials and continuous film materials according to their morphology, and metal materials and non-metallic materials according to their properties. Widespread use of magnetic recording medium is Γ-Fe2O3 material, in addition to CrO2, Fe,-Co and Co-Cr material and so on.Magnetic head materials mainly include Mn-Zn, Ni-Zn ferrite, Fe-Al, Ni-Fe-Nb and Fe-Al-Si alloy materials. Xinkang is a professional producer of Iron Cobalt FeCo sputtering targets, customers can obtain goon FeCo thin film by PVD technology.
The picture below are two micrographs of our FeCo(70/30 wt%) alloy sputtering target, the average grain size＜100μm.
The FeCo sputtering targets we produced are high purity, and alloy composisiton can be customized accorrding to your requirement, it’s most important benefits are that your films possess an outstanding level of electrical conductivity and minimized particle formation during the PVD process.
Below form is a typically Certificate of analysis for 3N5 high purity FeCo(70/30wt%)sputtering target.The analytical methods used are: 1. Analysis of metal elements using ICP-OES; 2. Analysis of gas elements using LECO.
