Remanence
If it must be distinguished from other kinds of remanence, then it is called the saturation remanence or saturation isothermal remanence (SIRM) and denoted Anhysteretic remanence
Another kind of laboratory remanence is anhysteretic remanence or anhysteretic remanent magnetization (ARM).

Data remanence
The section on complications gives further explanations for causes of data remanence. Data remanence has also been observed in dynamic random-access memory (DRAM).

Coercivity
The remanence coercivity, , is the H field required to reduce the remanence to zero, meaning that when the H field is finally returned to zero, then both The saturation remanence and coercivity are figures of merit for hard magnets, although maximum energy product is also commonly quoted.

Isothermal remanence
Some remanence calculations for randomly oriented, identical particles are shown in Figure 5. The other two types of remanence involve demagnetizing a saturation isothermal remanence (SIRM), so in normalized units they start at .

剩磁
若需要和其他的剩磁区分,这种剩磁会称为饱和剩磁(saturation remanence)或饱和等温剩磁(saturation isothermal remanence,SIRM),符号为Mrs。
在工程应用中会用量测剩磁,B-H分析仪是量测在交流磁场下的响应。 这称为退磁剩磁(demagnetization remanence,DC demagnetization remanence),以Md(H)表示,其中H为磁场的大小。

Natural remanent magnetization
Some kinds of remanence are undesirable and must be removed before the useful remanence is measured. The most important component of remanence is acquired when a rock is formed.

Thermoremanent magnetization
This remanence can also be very stable, lasting without significant change for millions of years. In the early 20th century, a few investigators found that igneous rocks had a remanence that was much more intense than remanence acquired in the Earth's

Viscous remanent magnetization
Viscous remanent magnetization (abbreviated VRM), also known as viscous magnetization, is remanence that is acquired by ferromagnetic materials by sitting magnetization (NRM) acquired in the Earth's field at one time, and is the equilibrium magnetization in a different field at some later time, the change in remanence

Nanomagnet
In magnetism, a nanomagnet is a nanoscopic scale system that presents spontaneous magnetic order (magnetization) at zero applied magnetic field (remanence The ultimate limit in miniaturization of nanomagnets was achieved in 2016: individual Ho atoms present remanence when deposited on a atomically thin
