A high current pulse generator for magnetizing thin magnetic films
A bipolar, high‐current (10 000 A) pulse generator, used to magnetically saturate thin films during spin‐polarized electron and dynamic response measurements, is described. Bipolar operation is achieved by discharging a bank of capacitors through selected pairs of high‐power silicon‐controlled recti...

| Zusammenfassung: | A bipolar, high‐current (10 000 A) pulse generator, used to magnetically saturate thin films during spin‐polarized electron and dynamic response measurements, is described. Bipolar operation is achieved by discharging a bank of capacitors through selected pairs of high‐power silicon‐controlled rectifiers connected to a coil in an H bridge configuration. The pulse generator can be controlled either manually or by means of a computer. |
