在本文中，我们简要回顾了东京大学兆高斯实验室（MGL）的设备，并概述了MGL在兆高斯磁场中固态物理学的重点成果。兆高斯实验室历史悠久，自1972年建立第一个原型以来，一直致力于探索在极高磁场极限下可能出现的新现象。从那时起，它在过去的三十年中取得了成功的发展，并且就在1999年，它在柏市新校区进行了扩建和更新。在MGL，脉冲高磁场通过三种不同的技术产生：电磁通量压缩（EMFC）、单匝线圈（STC）技术以及无损长脉冲磁体。通过EMFC已经获得了622特斯拉的最高磁场。通过STC技术，在具有水平和垂直线圈轴的两个系统中，根据线圈孔径的不同，已经获得了超过300特斯拉的极高磁场。这些磁场被应用于许多不同类型的实验，例如光学光谱学、回旋加速器和电子自旋共振、磁化以及输运测量。由绕线线圈产生的高达近70特斯拉的无损长脉冲磁场也是可用的。
We present in this paper a brief review of the facilities of the Megagauss Laboratory (MGL) of the University of Tokyo, and an overview of the highlights of solid state physics in megagauss fields at MGL. The Megagauss Laboratory has a long history since the first prototype was established in 1972 in order to pursue new phenomena which may occur in the extreme high magnetic field limit. Since then, it has achieved successful development in the last three decades, and very recently in 1999, it was enlarged and renewed at the Kashiwa new campus. At the MGL, pulsed high magnetic fields are produced by three different techniques: electromagnetic flux compression (EMFC), the single-turn coil (STC) technique, and non-destructive long pulse magnets. The highest magnetic fields of 622 T has been obtained by EMFC. By the STC technique, very high fields exceeding 300 T have been obtained depending on the coil bore, in two systems with horizontal and vertical coil axes. These fields are applied in many different kinds of experiments, such as optical spectroscopy, cyclotron and electron spin resonance, magnetization and transport measurements. Non-destructive long pulse fields up to nearly 70 T from wire-wound coils are also available.
