铁氧体磁性[Ferrimagnetism] [2005-9-8]
iamet 发表在 Ω〖物理〗
| | A property exhibited by materials whose atoms or ions tend to assume an ordered but nonparallel arrangement in zero applied field below a certain characteristic temperature known as the Néel temperature. In the usual case, within a magnetic domain, a substantial net magnetization results from the antiparallel alignment of neighboring nonequivalent sublattices. The macroscopic behavior is similar to ferromagnetism. Above the Néel temperature, these substances become paramagnetic. |
