【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.更多还原

【Abstract】 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.更多还原
