Coercivity is a property of magnetized materials and is the amount of magnetic field needed to bring a material's magnetization to zero. Basically, it's how much a material likes being magnetic.

Magnetic coercivity—the strength of magnetic field required to demagnetize a domain—must be high enough to prevent the separately recorded grains from influencing one another and corrupting data.

Combining with ab-initio calculations and micromagnetic simulations, we will predict the ideal microstructure to achieve the highest coercivity. Based on these experimental and modeling results, we ...

The higher a magnetic disk's coercivity index, the more data it can store. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

March 25, 2014. Researchers from North Carolina State University have found a way to reduce the coercivity of nickel ferrite (NFO) thin films by as much as 80% by patterning the surface of the ...

It is the common alignment of these crystals during fabrication that produces the strong field of the bulk magnet. The resilience of the arrangement results in the material’s high coercivity. To ...

Heat can jumble these magnetic bits and destroy the data. The latest disks use materials with a very large coercivity -- a measure of how difficult they are to demagnetize. However, write heads ...

1, 2 The magnetic behavior of the steel is governed by its composition, microstructure, and processing, resulting in specific properties such as permeability (the ability to conduct magnetic flux), ...

In approximately 15 seconds, the ME-P3M quietly erases data from longitudinal magnetic recorded (LMR) and perpendicular magnetic recorded (PMR) hard disk drives with nominal coercivity ratings of ...
