內容簡介
本書的目的是對磁性材料研究的新近進展提供一種全面的理解。本書共分四卷,每一卷集中論述一個具體的研究領域。每一章首先對該章的基本概念和重要觀念進行闡述,然後從實驗和理論方面進行詳細地說明,最後介紹該領域的發展前景以及新的思想。書中提供了詳盡的參考文獻,可供研究人員參考。
近年來納米磁性材料的研究十分活躍,例如,顆粒體磁性材料的磁矯頑力隨顆粒尺寸的減小而增大,到臨界尺寸後又減小。為取得最佳磁耦和強磁體,其中的軟磁相尺寸必須小於硬磁相磁籌界厚度的兩倍。當顆粒尺寸減小到幾個納米時,量子效應必需考慮。第1卷重點闡述納米尺寸效應對磁性材料的性能影響。
本書的讀者對象為研究生和相關專業的研究人員。
