用于低温和高磁场下磁化测量的微型电容式法拉第磁力仪
Miniature capacitive Faraday force magnetometer for magnetization measurements at low temperatures and high magnetic fields
摘要：
本文介绍了一种法拉第磁力仪，用于测量温度低至100 mK，磁场高至14 T的磁化强度。将样品安装在柔性悬臂上，形成与固定背板组合的力传感电容器。两种不同的悬臂梁设计。抗扭转悬臂梁允许测量高度各向异性的单晶样品的磁化强度。对金属有机量子磁体（C $_5$ H $_{12}$ N）$_2$ CuBr $_4$（BPCB）和NiCl $_2$ $\cdot$ 4 SC（NH $_2$）$_2$（DTN）的测量证明了该器件的能力。此外，测量样品的磁矩的分辨率优于$10^{-7}$ A $\,$ m $^2$（$10^{-4}$ emu）。该装置在小型化，以适应几乎任何低温恒温器。
英文摘要：
A Faraday force magnetometer is presented for measurements of magnetization at temperatures down to 100~mK and in magnetic fields up to 14~T. The specimen is mounted on a flexible cantilever forming a force-sensing capacitor in combination with a fixed back plate. Two different cantilever designs are presented. A torsion resistant cantilever allows to measure magnetization of highly anisotropic single crystal samples. Measurements of the metal organic quantum magnets (C$_5$H$_{12}$N)$_2$CuBr$_4$ (BPCB) and NiCl$_2$$\cdot$4 SC(NH$_2$)$_2$ (DTN) demonstrate the device's capabilities. Routinely, a specimen's magnetic moment is measured with a resolution better than $10^{-7}$ A$\,$m$^2$ ($10^{-4}$ emu). The device in miniaturized to fit is almost any cryostat.
