Erbium
Er symbol
its is usually found in combination with other elements.
A trivalent element,
pure erbium metal is malleable
soft yet stable in air,
does not oxidize as quickly .
Its salts are rose-colored, and the element has characteristic sharp
absorption spectra bands in visible light, ultraviolet, and near infrared.
. Its sesquioxide is called
erbia.
Erbium is ferromagnetic below 19 K,
antiferromagnetic between 19 and 80 K and paramagnetic above 80 K.
Erbium can form propeller-shaped atomic clusters Er 3N, where the distance between the erbium atoms is 0.35 nm.
Those clusters can be isolated by encapsulating them into
fullerene molecules, as confirmed by
transmission electron microscopy .
