摘要: We present a measurement system incorporating a superconducting quantum interference device (SQUID) and planar gradiometers for detecting small magnetization signals from the sample placing at low temperature (down to 1.5 K) and in high magnetic field (up to 14 T). The SQUID is from STAR Cryoelectronics. We have designed and fabricated a planar gradiometer to cancel the background magnetic field and noise. We measured the variation of the magnetic dipoles of a GaAs chip at 1.5 K in strong magnetic fields. However, the observed variation of the magnetic moment is different from what is expected theoretically. We provide suggestions to improve the measurement system for better results.
我們使用由STAR Cryoelectronics 所製造的超導量子干涉儀配合上特別設計的平面梯度計,架構一組能在1.5 K 低溫及14 T 高磁環境下做操作的量測系統,其中平面梯度計是為了將外界背景雜訊去除。並使用此系統量測在1.5 K 低溫環境下,提供均勻的時變磁場於GaAs 基板上,其磁矩對外加磁場的變化,用以測試系統實際操作情況。所得結果和理論預期不盡相同,這是在後續系統所需要繼續修正的地方。
