Second, atoms of rare earth elements can have high magnetic moments because their saturation magnetization " J " s ).
2.
In a thin soft phase, it is hard for the external field to rotate the magnetic moments, similar to a hard magnet with high saturation magnetization.
3.
These samarium cobalt magnets generally have a reversible temperature coefficient of-0.05 % / �C . Saturation magnetization can be achieved with a moderate magnetizing field.
4.
The magnitude of this moment is \ mu = V M _ s, where V is the volume of the particle and M _ s is the saturation magnetization.
5.
The presence of the magnetic nanoparticles allowed, first of all, the guiding of the nanotubes to specific locations in the body by external magnetic fields . "'Super paramagnetic particles "'are known to display strong interactions with external magnetic fields leading to large saturation magnetizations.
