How does one can calculate the exponent 'n' and the temp. dependent factor A(T) from AC conductivity Vs. frequency plot?

Generally for ferrite sample we use the dielectric data to find out the ac conductivity by the relation-σAC = e0erw tand. The ac conductivity can be also written as σ'= σDC + σAC, where σAC =...
