the appearance of an ordered spin state (magnetization) at zero applied magnetic field in a ferromagnetic or ferrimagnetic material below a critical point called the Curie temperature or .

Magnetization transfer, in NMR and MRI, refers to the transfer of nuclear spin polarization and/or spin coherence from one population of nuclei to another population of nuclei, and to techniques that make use of these phenomena.

The magnetization of an igneous rock that was acquired at the time it cooled from the molten state; it provides information on the Earth's magnetic field at that time.
