Samarium Cobalt (SmCo) Magnets and Neodymium Iron Boron (NdFeB) magnets are collectively known as Rare Earth magnets. SmCo Magnets are more expensive than the NdFeB and has a lower MGO value, between 24MGOe-28MGOe.  However, Samarium Cobalt does offer higher working temperatures up to 575 degrees F.
