A silver white lanthanide,
a metal of interest indeed.
Paul-Émile Lecoq de Boisbaudran,
made the discovery run.

From Samarskite, a russian ore,
in there hid one element more.
Altough it is quite rare,
it can be found everywhere.

Samarium has some special qualities,
probably caused from some abnormities.
Together with Cobalt it is a permanent magnet,
especially in a high temperature set.

Second at room temperature,
but at seven hundred your option for sure.
Music instruments, headphones, small motor device,
but Samarium magnest have their price.

Another specialty is being a chemical agent,
the rules of organic chemistry bent.
Samarium helps removing Hydrogen selective,
making the particular carbon reactive.

Samarium metal is a neutron absorbing material,
and as all isotopes are quite good, it is ideal.
This is the major aid for humanity,
Samarium and its specialty.

Three talents, completely different,
not so known, but yet present.
Samarium a rule braker,
a catalyst and a regulator.
