Manganese(II) fluoride is the chemical compound composed of manganese and fluoride with the formula MnF₂. It is a light pink crystalline solid, the light pink color being characteristic for manganese(II) compounds. It is made by treating manganese and diverse compounds of manganese(II) in hydrofluoric acid. It is used in the manufacture of special kinds of glass and lasers. .^[2] It is a canonical example of uniaxial antiferromagnet (with Neel temperature of 68 K ^[3]) which has been experimentally studied since early on.^[4]
