In a paramagnetic material the cancellation of magnetic moments between electron pairs is incomplete and hence magnetic moments exist without any external magnetic field. However, the magnetic moments are randomly aligned and Highenergy hard magnetic materials like Nd 2Fe 14B, SmCo 5 exhibit BH max 80 kJ/m3.

definition hard magnetic material Winner Science

Hard magnetic materials are those which have high coercivity, high retentivity and low loss in magnetisation due to mechanical treatment and no effect of temperature. These materials are called hard because these are difficult to magnetise and demagnetise. The higher the value of coercive force the harder is the magnetic material.

The platters are the most important parts of a hard drive. As the name suggests, they are disks made from a hard material such as glass, ceramic, or aluminum, which is coated with a thin layer of metal that can be magnetized or demagnetized. A small hard drive typically has only one platter, but each side of it has a magnetic coating.
