polarization for au/pb(zr ti )o /yba cu o ferroelectric capacitor has been studied and measured by pulse method. a sequence of pulses with amplitudes varying from 0 to 10 volts in 2 volt steps is applied and a conventional polarization curve is obtained by integrating the charge flow from the polarization switching induced by the voltage ramp. a value of 25?c/cm2 is measured for the saturated p...

The generalized effective-medium theory of induced polarization (GEMTIP) is a newly developed relaxation model that incorporates the petro-physical and structural characteristics of polarizable rocks in the grain/porous scale to model their complex resistivity/conductivity spectra. The inversion of the GEMTIP relaxation model parameter from spectral-induced polarization data is a challenging is...

SUMMARY Thanks to the emergence of new technologies developed with goal performing large-scale galvanometric induced polarization surveys and thanks a better understanding underlying physics polarization, this geophysical method can now be applied in field volcanology geothermal resources assessment. A approach is here for directly inverting primary secondary electric fields recorded at set ind...
