Saturation Magnetization
Note magnetic parameter: Saturation Magnetic saturation is the state reached in a sample when increases in applied external magnetic field H cannot increase the magnetization of the material further. At saturation, the total magnetic flux density B does not increase with increases in applied external fields. Saturation is a characteristic of ferromagnetic and ferrimagnetic materials, such as iron, nickel, cobalt and their alloys. Saturation is most…

SEM (Scanning Electron Microscope)
Scanning electron microscopy (SEM) is a very high imaging magnification performed with an electron microscope that produces informative images of magnetic samples by scanning them with a focused beam of electrons. The electrons interact with atoms in the sample, producing highly magnified images of the sample’s surface topography and composition. Image Magnification from an SEM can be controlled from 10 to…
