Abstract
At piezoelectric resonance, the "best" admittance circle is obtained by a n
onlinear square fit (a Newton-Raphson method) of the experimental points an
d is compared to a linear square fit. The piezoelectric coefficients are th
en computed by the motional capacitance method. Application to Mn-I boracit
