(er'sted),
A unit of magnetic field intensity; the magnetic field intensity that exerts a force of 1 dyne on a unit magnetic pole; equal to (1000/4π) A m-1.

oersted

(ĕr′stĕd)
[Hans Christian Oersted, Danish physicist, 1777–1851]
A unit of magnetic field intensity. An oersted is the magnetism that exerts a force of one dyne on a unit magnetic pole. This term has largely been replaced by the SI unit amperes per meter.

However, due to the scarcity of RE magnetic metals such as Dy-dysprosium, Pr-praseodymium, and Sm-samarium, a more practical approach, which seems to be gaining more ground, is manipulation on the structure of grain boundary phases and internal interfaces, which enable better understanding of relevant coercivity mechanisms.
