Another rare earth lanthanide,
was first found at Hollmiums side.
A french scientist did the job,
well done Mr. Lecoq.

Dysprosium means hard to get,
which tells us everything I would bet.
Eighteenhundreteightysix,
he had to use a lot of tricks.

Nowadays with ion exchange,
which probably sounds a little strange.
It is not so difficult to get it clean,
the annual production is a small stream.

Hard to get, rare earth, you might wonder,
what is it for this plunder.
Three things should be mentioned here,
quite usefull they might appear.

In first place its all about magnets,
in high magnetic sets.
Not magnetic on its own,
combined with iron, a superpower is shown.

Electric vehicles, wind turbines,
is where Dysprosium shines.
As a second application,
a D-YAG L.A.S.E.R is a sensation.

Last but not least it is used in detectors,
for ion radiation spectators.
In otherwords in dosimeter,
if unknown google it later.

With electric car demand,
the need of this element expand.
It might help us to get a little green,
but the effort to get it is still extreme.

Hard to get, almost twohundret years,
a good name it appears.
Another metal for our civilization,
helps us in high end creation.
