Picosecond pulsed magnetic fields for studies of ultrafast magnetic phenomena

Abstract

Ultrafast optical techniques were used to develop novel time-resolved probes of magnetic dynamics. Picosecond-scale magnetic field pulses were launched from a photoconductive switch and applied to small samples which were then probed by time-delayed optical pulses, yielded temporal information in a conventional stroboscopic manner. Characteristics of the magnetic field pulses are described and illustrated through measurements of rapid relaxation effects in europium sulfide films at low temperatures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
