Ferromagnetic materials seeAlso The table on the right lists a selection of ferromagnetic and ferrimagnetic compounds, along with the temperature above which they cease to exhibit spontaneous magnetization (see Curie temperature ).
As the iron passes through the Curie temperature there is no change in crystalline structure, but there is a change in "domain structure", where each domain contains iron atoms with a particular electronic spin.
Its Curie temperature is convert, meaning that bulk nickel is non-magnetic above this temperature. citation The unit cell of nickel is a face-centered cube with the lattice parameter of 0.352 nm, giving an atomic radius of 0.124 nm.
Superparamagnetism is different from this standard transition since it occurs below the Curie temperature of the material.
Therefore, below the Curie temperature virtually all of the dipoles in a ferromagnetic material will be aligned.
