Magnetic materials [Encyclopedia Magnetica™]

The "softness" in the name refers to their magnetic response (ferromagnetism or ferrimagnetism), as they can be easily magnetised and demagnetised (especially when compared to "hard" materials).The B-H loop is narrow, so that the coercivity values are low. For example the standard IEC 60404-1 defines magnetically soft materials as such that have coercivity H c below 1000 A/m.

Magnetic Properties of Materials

The terms hard magnetic and soft magnetic originate from the early days of research and use of magnetic materials. For metals, the rule was that low H C and B r values were associated with mechanically soft materials. If necessary, a reduction of these values could also be achieved with a Fe-alloy, for example, by soft annealing.

Soft Magnetic Nanocrystalline Alloys: Materials

Permanent magnets require the magnetization vs. field hysteresis loop, M(H), to be broad, with a large coercive field in order to allow energy to be stored in the material. In contrast, soft magnetic materials require a narrow hysteresis loop, which implies the use of small amounts of energy to magnetize the material.
