摘要	Recently we have developed a spin Hall magnetoresistance (SMR) sensor which operates under AC bias and sense currents. Here we demonstrate both theoretically and experimentally that the SMR sensor is uniquely suited for eddy current testing applications because both the coil and sensor utilize AC current as the excitation source. The use of SMR sensor effectively eliminates the necessity of any demodulation or lock-in technique for detecting the eddy current, which greatly simplifies the detection system. Furthermore, we show that the combination of principal component analysis and decision tree model is effective in classifying the metal cracks. The relatively clean signals obtained by the SMR sensor greatly facilitates the subsequent signal analysis and ensures high accuracy in the classification of different types of crack features.
