Minerals that are diamagnetic or paramagnetic only have an induced magnetization. Three measured paramagnetic complexes measured significantly lower than the diamagnetic metallo-texaphyrins. The case of a paramagnetic or diamagnetic dipole is considered first. Diatomic gases are also almost exclusively diamagnetic, and not paramagnetic. Only ferromagnetic, antiferromagnetic, and diamagnetic materials can satisfy this condition. In varying temperatures, antiferromagnets can be seen to exhibit diamagnetic and ferromagnetic properties. Ruthenium forms dichalcogenides, which are diamagnetic semiconductors crystallizing in the pyrite structure. Compounds which are expected to be diamagnetic may exhibit this kind of weak paramagnetism. They are usually colorless or orange, diamagnetic anions. A substance that is diamagnetic repels a magnetic field. This means that diamagnetic materials are repelled by magnetic fields. Like many of the smaller boron hydrides, pentaborane is colourless, diamagnetic, and volatile. No other metal is verified to be more naturally diamagnetic than bismuth. This involves the use of diamagnetic or electromagnetic levitation to float an object. The diamagnetic nature of the ion confirms its dimeric structure.
