paramagnetism,英語單詞,主要用作名詞,作名詞時譯為“[物] 順磁性;常磁性”。
順磁性(paramagnetism)是指材料對磁場回響很弱的磁性。如用磁化率 k= M / H 來表示(M 和 H 分別為磁化強度和磁場強度),從這個關係來看,磁化率k是正的,即磁化強度的方向與磁場強度的相同,數值為10~10量級。一些原子核(如1H,7Li,11B,13C,17O等以及中子)具有磁矩,在磁場作用下會產生順磁性,...
一般物質置放於磁場中,由於感受磁場強度的方式不同,可區分成逆磁性(diamagnetism)、順磁性(paramagnetism)和鐵磁性(ferromagnetism)三大類。這三大類物質在磁場中的反應可由外加磁場強度H與物質受磁場影響感應而生的磁強密度J的關係區分開來,J與H的比值即為感磁率。相關概念 ——J-H關係 如圖《物質的J-H...
超順磁性(Superparamagnetism)是指顆粒小於臨界尺寸時具有單疇結構的鐵磁物質,在溫度低於居里溫度且高於轉變溫度(Block Temperature)時 表現為順磁性特點,但在外磁場作用下其順磁性磁化率遠高於一般順磁材料的磁化率,稱為超順磁性。臨界尺寸與溫度、材料有關,鐵磁性轉變成超順磁性的溫度常記為T,稱為轉變溫度。...

garnet,釔鐵石榴石)和亞鐵鹽組成。該亞鐵鹽由鐵氧化物和其他元素,例如鋁、鈷、鎳、錳、鋅組成。順磁性 順磁性(Paramagnetism)指的是一種材料的磁性狀態。有些材料可以受到外部磁場的影響,產生跟外部磁場同樣方向的磁化矢量的特性。這樣的物質具有正的磁化率。與順磁性相反的現象被稱為抗磁性。參見 磁化曲線 ...
順磁性(Paramagnetism)指的是一種材料的磁性狀態。有些材料可以受到外部磁場的影響,產生跟外部磁場同樣方向的磁化矢量的特性。這樣的物質具有正的磁化率。與順磁性相反的現象被稱為抗磁性。順磁性物質可以被看作是由許多微小的磁棒組成的,這些磁棒可以旋轉,但是無法移動。這樣的物質受到外部磁場的影響後其磁棒主要順...
