coercivity
- noun
- /koʊˈɜːrsɪvɪti/
- Specialized
- (Coercivity is the strength of the applied magnetic field needed to permanently change the direction of the magnetization of a material.)
Examples
-
That approach offers a better combination of coercivity, grain size, and thermal stability than can be achieved with single-layer media; it thus allows higher-density recording.
Academic text (2002) -
The coercivity of a magneto-optic material remains high until it has almost reached the Curie temperature.
Academic text (1996) -
This may adversely affect the recording performance from low coercivity and poor signal-to-noise ratio.
Academic text (1996) -
In short, HMR works by leveraging high coercivity media and localised plasmonic heating.
-
The magnetic film, a cobalt alloy with chromium and coercivity-controlling elements such as platinum or tantalum, is sputtered next.
Academic text (1996) -
The coercivity of certain magnetic materials enhances their stability in electronic devices under varying conditions.
-
Engineers test the coercivity of magnets to ensure they maintain their magnetization in strong external fields.
-
High coercivity materials are essential for developing reliable data storage systems that withstand magnetic interference.

Etymology
The word coercivity comes from coerce, which means 'to force', and the ending -ivity that names a quality. Think of a magnet as stubborn when someone tries to make it change, so coercivity is the magnet's power to resist being forced to change its magnetic state.
