when expressed per unit of volume.
Typically, the natural
remanent magnetisation of a baked clay is in the
order of 1 A/m and of a sediment 10-3 A/m.
times metres squared. Unit of the magnetic moment.
times metres squared per kilogram. Unit of magnetisation when expressed
per unit of weight.
remanent magnetisation (ARM)
magnetisation imparted to a sample in the laboratory by applying a
magnetic field in the
presence of a steady magnetic

(see also ferromagnetism). Form of
ferromagnetism in crystalline material with two oppositely and equally
magnetised sublattices. The

Antiferromagnetics become paramagnetic (see also paramagnetism) beyond

ferromagnetism, e.g. in goethite,
haematite) or because of an imperfect
antiparallelism of the magnetic moments (canted antiferromagnetism,

This period is characterised by the
