Default motor builders question

Which magnet has a higher coercive number? Samarian Cobalt or Rare Earth?

And are either of these used in our racing motors?

The term 'Rare Earth' covers a number of elements and amongst these elements are neodymium and samarium, both of which have been used in electric motors.
Neo is used in brushless motors in either bonded on sintered form. None of the major players currently makes a 'rare earth' brushed motor but at least one has in the past but this was mainly for the flight market, might have also done one for the drag market. From what I can remember they were very expensive, the can cost more than a entire mod motor.
