摘要:
A simple microvibrating sample magnetometer (MVSM), particularly inexpensive, sensitive, and versatile has been developed. An alternating magnetic field superposed to a steady uniform magnetic field is applied to the sample. The sample undergoes a periodic motion around an equilibrium position, causing a pressure fluctuation within a closed gas cell which is detected as an acoustic signal by a microphone.
