New rare earth permanent magnet

The new rare earth permanent magnet is a new magnetic alloy that can replace the traditional rare earth permanent magnet created by Karl and other scientists at Ames Energy Laboratory in April 2015.
A new alloy - a potential replacement for a high volume permanent magnet - uses the most abundant cerium instead of the rare Dy.
NdFeB permanent magnets made of cerium and cobalt are a cheaper material, but perform as well as traditional sintered permanent magnets containing DY.
Ames experiment shows that the intrinsic coarseness of cerium-containing alloy is much higher than that of permanent magnet containing DY at high temperature.
This material is at least 20-40% cheaper than permanent magnets containing DY.
This is a very exciting result. This material works at 150 degrees Celsius, which is better than anything currently available. Best suited for high temperature
