Time relaxation of ac susceptibility on very short time scales
We present an experimental method enabling measurements of time dependence of ac susceptibility down to 1 ms after a steplike change of the applied dc magnetic field. An analog-digital converter has been used to collect the transient of the current, signaling the change of the dc magnetic field. The time window for investigation of magnetic time relaxation phenomena, as studied by the ac susceptibility technique, thus has been expanded in the range of short time scales for three orders of magnitudes.
