摘要：

Recently the ferrimagnetic iron sulphide greigite (Fe3S4) has been recognized as an important carrier of magnetic remanence in young sediments. New magnetic measurements and properties of this rare mineral are presented. Magnetic domain observations were made using the Bitter method and the magneto-optical Kerr effect. In most cases the domain structures observed are very complicated and their interpretation is rather difficult. The cause of this domain structure is very likely high magnetostriction. A first attempt to establish a relationship between grain size and domain state is made.
