强磁场下的物理研究是一个富有成果的研究领域 .4 0T以上稳态强磁场的研制成功为固体物理研究提供了新的科学机遇 .文章简要地介绍强磁场下某些固体物理 ,其中包括高温超导体的H -T相图和非费米液体行为 ,德哈斯 (deHaas)效应和费米面性质 ,电子的Wigner结晶及其动力学行为 ,磁场诱导的相变 (如绝缘体 -金属和超导转变 ) ,多级磁有序 ,串级自旋密度波和大块材料中的量子霍尔效应等的实验研究的近期进展 ,希望以此引起人们对国内强磁场下物理研究的关注 .

The physics of high magnetic fields is a subject rich in achievements. Steady high magnetic fields above 40T have been successfully developed, providing new opportunities for studying solid state physics under such fields. An overview is presented of recent progress in this area, including the H\|T phase diagram and non\|Fermi liquid behavior of high temperature superconductors, the de Haas effect and properties of the Fermi surface, Wigner crystalligation of electrons and its dynamical properties, magnetic field\|induced phase transitions such as insulator\|metal and superconductor transitions multistage magnetic ordering, successive spin density waves and the quantum Hall effect in bulk material.
