As a result, manganese is atomically paramagnetic. It will show molar magnetic susceptibility of value (α) +529.0×10 −6 cm 3 /mol (293 K). Solid manganese is anti-ferromagnetic because, in the solid state, the magnetic moments of the two spin states combine and effectively cancel out the magnetic fields.
Manganese, Physical and Chemical Properties | SpringerLink
Manganese is a silver-gray metal, resembling iron. It is hard and brittle, and its primary uses in a metallic form are as an alloying, desulfurizing, and deoxidizing agent for steel, cast iron, and nonferrous metals. It is a transition metal; hence, it is less reactive than the typical metals and more reactive than the less-typical metals.
