چکیده انگلیسی
In this paper, we present a quasi-static charge amplifier method to detect the extremely low frequency response of Metglas/Pb(Mg1/3Nb2/3)O3–PbTiO3 magnetoelectric (ME) laminated composites. Using this technique, ME effect can be detected at f<10−2 Hz, and ME charge coefficients show good stability over wide frequency range from 10 mHz to 1 kHz. Thus, it allows us to develop a quasi-static magnetic sensor based on ME composites which can work at frequencies as low as 10 mHz, with equivalent magnetic noise floors of about 3 nT/√Hz.
► We have designed the quasi-static frequency magnetic sensor.
► Noise model for the sensors is developed.
► Low frequency responses of sensors are characterized.
