Extreme pressures and high magnetic fields can affect materials in profound and fascinating ways. However, large pressures and fields are often mutually incompatible; the rapidly changing fields provided by pulsed magnets induce eddy currents in the metallic components used in conventional pressure cells, causing serious heating, forces, and vibration. Here, we report a diamond-anvil-cell made mainly out of insulating composites that minimizes inductive heating while retaining sufficient strength to apply pressures of up to 8 GPa. Any residual metallic component is made of low-conductivity metals and patterned to reduce eddy currents. The simple design enables rapid sample or pressure changes, desired by pulsed-magnetic-field-facility users. The pressure cell has been used in pulsed magnetic fields of up to 65 T with no noticeable heating at cryogenic temperatures. Several measurement techniques are possible inside the cell at temperatures as low as 500 mK.

脉冲磁铁复合压力传感器

极高的压力和强磁场会以深刻而迷人的方式影响材料。然而，巨大的压力和领域常常相互矛盾。脉冲磁铁提供的快速变化的磁场在常规压力传感器中使用的金属部件中感应出涡流，从而引起严重的发热，力和振动。在这里，我们报道了一种主要由绝缘复合材料制成的金刚石-砧式电池，可将感应加热降至最低，同时保持足够的强度以施加高达8 GPa的压力。任何残留的金属组件均由低电导率的金属制成，并进行构图以减少涡流。简单的设计可实现快速采样或压力变化，这是脉冲磁场设备用户所希望的。压力传感器已用于高达65 T的脉冲磁场中，在低温下没有明显的加热。在低至500 mK的温度下，电池内部可以采用多种测量技术。
