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.

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).

In nickel-iron alloys, a compensation of positive and negative values of magnetostriction can be achieved. The zero-crossing of magnetostriction occurs in an alloy containing approximately 83% nickel. For iron-nickel alloys with 36% nickel, the Curie temperature T C is close to room temperature. In this temperature range, there is therefore a ...
