Then the discs and the small blocks of soil attached beneath them are carefully removed.In the lab afterwards, the difference in orientation between the line showing the present magnetic pole and the orientation of the magnetised particles in the soil, reflecting the pole's position at the time of burning, can be determined.Antiferromagnetism A form of ferromagnetism where the crystalline material contains two oppositely and equally magnetised sublattices so that the net magnetism will be zero.

The raw materials and proportions were carefully chosen to fulfil the mechanical necessities of the architectonic function: different proportions were found in plasters of floors, in the external walls, and inside the buildings; differences between earlier and later plasters were also detected.

An example of a canted antiferromagnetic mineral is haematite.

Archaeomagnetic dating Archaeomagnetic dating uses the ability of certain materials to record the Earth's magnetic field (geomagnetic field) to provide a date.

Archaeomagnetic dating relies on the measuring the orientation of iron particles in burnt deposits towards the magnetic pole.
