GB/T 19619 nanomaterials terminology
3 Terms and definitions
GB/T 19619 established and the following definitions of terms apply to the guidance of technical documents.
3.1
Magnetic moment magneticmoment
Under the action of the magnetic field can change and in turn affect the magnetic field of the medium, called the magnetic medium. For any magnetic material, it is generated by current
The smallest unit of magnetic moment is atom. The atom generates a magnetic moment by the spin of the electron and the movement around the nucleus. The direction of magnetic moment can be right
Hand rules to determine. Its expression see formula (1).
m➝j = A
ji (1)
In the formula.
m➝j --- magnetic moment vector, the unit is ampere square meter (A · m2);
j --- enclosed by the current i enclosed area vector, in square meters (m2);
i --- closed path current, in amperes (A).
According to the magnetic moment in the external magnetic field when the different performance, usually can be simply divided into the following three categories of objects.
a) diamagnetic material. When the external magnetic field, the object itself generated magnetization direction and the applied field opposite;
b) Paramagnetic substance. When the magnetic field is applied, the magnetization direction of the object itself is the same as that of the applied field.
c) Ferromagnetic material. When the applied magnetic field, the object itself produces a strong magnetization and the direction of the applied field. Ferromagnetic
Material is divided into soft magnetic and hard magnetism.
3.2
Magnetization
The total magnetic moment per unit volume of magnetizable material, its expression see formula (2).
M➝ = Σ
m➝j/V (2)
In the formula.
M-- --- magnetization vector, in amperes per meter (A/m);
V --- volume of magnetized material, in cubic meters (m3).
