Abstract :
In order to reduce the noise level of the second-harmonictype magnetic modulator, the authors propose a new method of modulation employing pulse-wave excitation at a temperature slightly below the Curie point. It is verified experimentally that the equivalent input noise could be reduced to 0.026 µAT/cm.
