Did You Know?
Samarium-cobalt magnets were the first type of high-strength rare-earth magnet developed and are the second-strongest type after neodymium magnets.
A key advantage of samarium-cobalt magnets is that they can withstand much higher temperatures than neodymium magnets before losing their magnetic properties.
The radioactive isotope samarium-153 is used in a medicine that targets and kills cancer cells, particularly in bone cancer.
Like many lanthanides, it was discovered spectroscopically from the mineral samarskite, which is how it got its name.
It is used in control rods in some nuclear reactors to absorb stray neutrons.
