SmCo5 Crystals with Magnetic Energy 32 Million Gauss-oersted
Ermolenko A.S., Korolev A.V., Shur Ya.S.
A single-domain state with magnetic energy 32 million G-Oe was obtained in bulky single crystals of SmCos by delaying the formation and growth of the magnetization-reversal nuclei. This is the theoretical limit of this material and never before attained in permanent magnets at room temperature.
