At the beginning, the magnetization is zero, but it begins to rise rapidly as the magnetic field is applied. At high field, the magnetic domains are aligned and the magnetization is said to be saturated. When the field is removed, a certain remanent magnetization (indicated as the point B r on the graph) is retained, i.e., the material is ...

Saturation Magnetization (Ms): If we start with non-magnetized specimen at zero magnetic field. With increasing magnetic field magnetization of the specimen increases and attains a maximum, such that there is no increment in magnetization if we increase magnetic field further. This maximum magnetization is known as saturation magnetization (Ms).

Urata et al. 22 found that bcc α-Fe (Si) nanostructures have better soft magnetic properties when Si is removed. This could explain the softer performance in coercivity of laser annealed samples. Among them, sample g demonstrates an optimum soft magnetic behavior, with a coercivity of 3.6 A/m and a saturation magnetization of 128.5 emu/g.

The Ni 0.5 Zn 0.5 Fe 2 O 4 composition has been selected because equal ratio between nickel and zinc gives the maximum saturation magnetization for this type of ferrites [26]. Whereas cobalt introduction into the Ni-Zn ferrite system can improve magnetic properties of the material due to positive magnetocrystalline anysotropy constant.

The amount of FeNi 3 phase was tuned by heating mode and amount of nickel precursor. The composites with higher amounts of FeNi 3 phase and larger sintered particles (0.4–0.8 μm) were synthesized by microwave heating. The highest value of saturation magnetization (81 emu/g) was attained in the NiFe 2 O 4-45 wt % FeNi 3 composite.

Note, that in order to get to saturation magnetization in a paramagnetic material one needs extremely high magnetic fields on the order of ~ 100 T (T=Tesla). However the largest magnets that have been experimentally achieved provide fields on the order of 10s of Tesla. Consequently, paramagnets never achieve saturation magnetization experimentally.
