    Silberberg (1998) explains that magnetic properties of minerals are affected by the chemical structure of the individual molecules. In order for a substance to be paramagnetic, it must have unpaired electrons in the molecular orbitals, while diamagnetic substances contain paired electrons in the molecular orbitals.

    Not All Iron Is Magnetic (Magnetic Elements)

    03.07.2019 · Iron isn't the only element that displays magnetism.Nickel, cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic.

Goethite crystals are made out of smaller crystallites of which magnetic properties are coupled by the interaction between crystallites (Mørup 1990; Coey et al. 1995).Over the last century, goethite has been identified in soils and sediments on Earth (e.g. Evans ...

    Mineral Gallery - The Magnetic Minerals

    The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions.
