Cobalt-based Hard Magnetic Films free essay sample

A highly technical paper that reviews literature on the operating procedure and magnetic properties of electrochemical deposited Co-based magnetic films. This report reviews literature on the operating procedure and magnetic properties of electrochemical deposited Co-based magnetic films. The significance and limitations of electrochemical deposit Co-based magnetic films are analyzed. Hard magnetic materials have been a focus of interest in electrical engineering for years because of their applications as media in recording and potential applications in fabricating magnetic MEMS devices due to the strong magnetic field produced by them in absence of applying magnetic field1.2. Besides the hard ferrites and Nd2Fe14 B1, Cobalt or Cobalt-RE based magnets are mostly used hard magnetic materials because of their good magnetic properties as well as their excellent mechanical properties1. Generally speaking, Cobalt based hard magnetic materials are fabricated by PVD methods such as RF sputtering or evaporation. However, it is likely to be time and money consuming to apply these procedures, especially for a relatively thick film, say, 20mm or more, is needed.
