熱剩磁 的英文怎麼說
中文拼音 [rèshèngcí]
熱剩磁
英文
thermoremanence-
X - ray diffraction results revealed that the structure of as - deposited smco film was amorphous and crystallization happened after the films annealed at 500 in vacuum. the magnetic tests of smco thin films showed that its coercivity reduced with the increase of film ' s thickness while the ratio of mr / ms was opposite. the films " coercivity and mr / ms declined after it annealed at 500 because the machanism of magnetization were changed from domain wall nailing into magnetic nuclear forming
研究結果表明,由於雜質fe的摻入降低了smco薄膜的磁性能;制備態smco薄膜為非晶態結構,矯頑力hc隨著薄膜厚度的增加而減小,剩磁比mr ms隨膜厚增加而增加;經過500真空退火熱處理后,薄膜出現smcos的結晶物,矯頑力hc降低, mr ms減小,磁化機制由疇壁釘扎類模型轉為形核類模型。Ii. hc and mr / ms rise with the extension of time, which also because the fcc texture changes into fct texture
(二)隨著熱處理時間的延長,矯頑力和剩磁比顯示出與( l )相同的變化趨勢,其解釋也是同樣的。I. hc is greatly improved from several oe to nine thousands oe with the rise of annealing temprature, but mr / ms decreases, which mainly because fcc texture changes into fct texture
熱處理溫度在600 850的范圍內,隨著的溫度的升高剩磁比稍有降低,主要原因是晶相結構的形成和fcc相到fct相的轉變。
