magnetic coercivity

magnetic coercivity

The amount of energy required to alter the state of a magnet. The higher a magnetic disk's coercivity index, the more data it can store.

In conventional neodymium magnets, dysprosium alloying is indispensable for enhancing magnetic coercivity. These simulation techniques offer a clear design rule for high-performance neodymium magnets that do not rely on dysprosium.

The result was a crystalline phase transition and magnetic coercivity enlargement.The results of the present study show that stable FePt nanoparticles form after being heated at 700oC in salt separation medium through ultrasonic process.
Tape media to date has had the magnetic coating somewhat thick (0.5[micro]m or more) compared to these dimensions combined with moderate magnetic coercivity which yields broad written transitions due to the generation of transitions curving into the depth of the magnetic coating and the demagnetizing effect of sizeable opposing magnetic regions.
