先進(jìn)磁性材料手冊(cè)第3卷

內(nèi)容概要

本書的目的是對(duì)磁性材料研究的新近進(jìn)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(gè)具體的研究領(lǐng)域。每一章首先對(duì)該章的基本概念和重要觀念進(jìn)行闡述，然后從實(shí)驗(yàn)和理論方面進(jìn)行詳細(xì)地說明，最后介紹該領(lǐng)域的發(fā)展前景以及新的思想。書中提供了詳盡的參考文獻(xiàn)，可供研究人員參考。    每種新磁性材料的開發(fā)成功都取決于它的性能與成本。在正確的磁理論建立后，如何使用最合適的制作加工工藝是開發(fā)制造新磁性材料的關(guān)鍵。第3卷對(duì)近年來各種磁性材料的制作加工原理和性能的相關(guān)性進(jìn)行分析總結(jié)并瞻望未來。    本書的讀者對(duì)象為研究生和相關(guān)專業(yè)的研究人員。
