Magnetic Properties of Typical Selected Meteorites

Meteorites are mainly magnetic materials which contain Iron alloys. The large number of mete-orites requires their classification and they can be classified within different approaches. The most frequent and simple method (based on their iron content and magnetic properties), is to divide them, into main three groups: (i) stony, (ii) stony-iron and (iii) iron meteorites. Meteor-ites are usually named after the places in the world where they fell. In general, scientific articles on meteorites are published in specified related journals, which are read by selected specialists who are interested in them. Practically, these articles describe the meteorites’ com-position, crystal structures and their various phases and obviously their physical properties in-cluding magnetic properties. In recent years, our group managed to perform extensive meas-urements (including magnetic studies) on several dozens of meteorites. Following the above classification, we aim to present the magnetic behavior of seven typical representative meteorites form the three mentioned groups, all published in the past. This article is intended and directed to non-expert scientists, for whom meteorites are not in their research field. Generally speaking, any meteorite is composed of two parts: (1) magnetic components (mainly Fe-Ni-Co alloys) with magnetic transition temperatures well above or below room temperature, (2) various paramag-netic components. The ratio between the two parts determines the meteorite property and its classification. The dominant magnetic character of the first part may overshadow the second part's magnetic properties.
