为了将高压和磁场的极端条件联合收割机结合起来，我们研制了一种非金属金刚石对顶砧，以避免在脉冲磁场中产生焦耳热。尽管电池在负载下变形，但可以施加约8.5 GPa的最大压力。用隧道二极管振荡器测量了重费米子反铁磁体CePt2In7在脉冲场中和常压下的量子振荡。详细讨论了CePt2In7的压力盒和场致费米面变化。
In order to combine the extreme conditions of high pressure and magnetic field, we have developed a non-metallic diamond anvil cell to avoid Joule-heating in a pulsed-magnetic field. Although the cell is deformed with loading, a maximum pressure of~ 8.5 GPa can be applied. Quantum oscillation measurements using tunnel diode oscillator have been performed for heavy fermion antiferromagnet CePt 2 In 7 in a pulsed field and at ambient pressure. The detail of the pressure cell and field-induced Fermi surface changes of CePt 2 In 7 are discussed.
