摘　　要：磁性材料是应用广泛、品种繁多的一类重要的功能材料,20世纪90年代以后发展十分迅速.稀土-3d过渡族磁性合金材料,如稀土永磁、巨磁致收缩材料、巨磁热效应材料,磁光效应材料等,以及非晶,纳米微晶磁性材料相继问世.1988年巨磁电阻效应的发现已获广泛应用,如读出磁头、传感器以及磁随机存储器等,并发展成为自旋电子学的新学科.文章简要介绍了近年来磁性材料的一些新进展.Magnetic materials are important functional materials which have wide applications and consist of a wide variety. The development of magnetic materials was extremely rapid during the 1990＇s, when magnetic alloys of the rare earth - 3d iron group, such as rare earth permanent magnets, giant magnetostriction materials, giant magnetocaloric materials, magnetooptic materials, magnetic amorphous materials, and nanocrystalline magnetic materials, appeared one by one. The discovery of giant magnetoresistance led to a new research domain - spintronics. Today it is used in various types of devices such as read - out heads, sensors and magnetic random access memories. An overview of new advances in the development of magnetic materials will be presented.
