Thermal stability of magnetoelectric sensors [PDF]

Applied Physics Letters, 2012
The effect of temperature on the equivalent magnetic noise floor of Metglas-Pb(Zr,Ti)O3 (PZT) laminate magnetoelectric (ME) sensors has been investigated in the temperature range of −50 °C to 50 °C. In detail, the parameters that control the noise floor of ME sensors, such as capacitance, tan δ, and ME charge coefficient, were characterized.
