1. Physics of superparamagnetism
1.1 Definitions
1.1.1 Polarization and magnetic moment
Magnetic polarization, J (in T), is a measure of the sum of atomic moments per unit volume with respect to a quantization axis. When all the moments are aligned in the same direction, particularly under the action of a strong magnetic excitation field H (A · m –1 ), the material is saturated and J = J S .
Polarization is equivalent to magnetization,...
