摘要:

在凝聚态物理、粒子物理、等离子体物理、化学和生物学研究等各个科学学科中,使用脉冲强磁场作为物理现象控制参数的兴趣日益增长。我们设计了一种简洁便携的脉冲磁场发生器,可产生40 T磁场,脉冲持续时间为2 ms。它仅使用现成组件和一个自制线圈组装而成,该线圈利用小型计算机、树莓派和Python代码。它便于针对一般用途进行直接修改。作为工作示例,我们展示了在凝聚态实验中分别对石墨、NdNi$_{2}$P$_{2}$和NdCo$_{2}$P$_{2}$进行的磁电阻、磁化和磁致伸缩测量的代表性应用,最大磁场为41 T,最低温度为4.2 K。

英文摘要:

There is a growing interest in using pulsed high magnetic field as a controlling parameter of physical phenomena in various scientific disciplines, such as condensed matter physics, particle physics, plasma physics, chemistry and biological studies. We devised a concise and portable pulsed magnetic field generator that produces a 40 T field with a pulse duration of 2 ms. It is assembled using only off-the-shelf components and a homemade coil that leverages small computers, Raspberry Pi, and Python codes. It allows for straightforward modification for general purposes. As working examples, we show representative applications in condensed matter experiments of magnetoresistance, magnetization, and magnetostriction measurements for graphite, NdNi$_{2}$P$_{2}$, and NdCo$_{2}$P$_{2}$, respectively, with the maximum magnetic field of 41 T and the lowest temperature of 4.2 K.
