The VSM (Vibrating Sample Magnetometer) option for the PPMS is a fast and sensitive DC magnetometer. The basic measurement is accomplished by oscillating the sample inside a detection (pickup) coil and synchronously detecting the voltage induced. The system is able to resolve magnetization changes of less than 10-6 emu at a data rate of 1 Hz thus allowing fast data acquisition. That makes this option suitable for taking data while sweeping magnetic field and/or temperature. This option does not measure AC susceptibility.
