A Peaker on Commercial High-Power Semiconductor Diodes for Exciting Free Magnetization Oscillations

摘要

A unit intended for shaping pulses of the magnetic field that initiate free magnetization oscillations in magnetic films is described. The unit consists of a peaker on a semiconductor diode and a differentiating RC circuit. It produces pulses with an amplitude of up to 10 Oe, a rise time of ≤0.3 ns, and a total length of ≤1 ns. The unit was used for studying free oscillations (in a 0.6- to 1.2-GHz frequency band) in ferrite-garnet films with easy-plane-type anisotropy.
