Departament de Fi ′ sica，Universitat Auto`noma de Barcelona，08193 Bellaterra，Spain~接收日期：1996年11月20日！本文研究了非晶态Co-P体系的晶化动力学以及样品的磁序对晶化产物的微观结构和磁性的影响。在加和动力学假设下，计算的温度-时间-转变（T-T-T）和温度-加热速率-转变（T-HR-T）曲线与实验数据符合得很好。扫描电子显微镜、X射线衍射和磁性测量表明，当样品的居里温度远高于晶化温度时，在晶化过程中，非晶样品的易磁化轴保持不变，并诱导出清晰的织构。这清楚地表明，磁序在该体系的结晶过程中起着重要的作用。@S0163-1829~97！05834-7#I.介绍
Departament de Fi´sica, Universitat Auto`noma de Barcelona, 08193 Bellaterra, Spain~Received 20 November 1996!The crystallization kinetics of the amorphous Co-P system and the influence of the magnetic order of thesamples on the microstructural and magnetic features of the crystallization product have been studied. Byassuming an additive kinetics, the calculated temperature-time-transformation (T-T-T) and temperature–heating-rate–transformation (T-HR-T) curves are in good agreement with the experimental data. Scanningelectron microscopy, x-ray diffraction, and magnetic measurements show that a clear texture is induced andthat the easy axis of the amorphous samples is preserved during the crystallization process for samples with theCurie temperature well above the crystallization temperature. This clearly shows that magnetic order plays animportant role in the crystallization in this system. @S0163-1829~97!05834-7#I. INTRODUCTION
