摘要：
With a controllable discharge of capacitors to coils, a series of positive and negative magnetic field pulses has been generated and was used to perform the magneto optical Kerr effect (MOKE) measurement on a Fe film. The realized maximum magnetic field strength is around one thousand oersteds and the pulse duration is around 1 ms. The total MOKE response is taken within 4 ms. This technique can be applied when a moderate magnetic field is needed but a strong electromagnet with iron core is not available or not suitable.
