Optimized Analysis of the AC Magnetic Susceptibility Data in Several Spin-Glass Systems using the Vogel-Fulcher and Power Laws

Mouli Roy-Chowdhury, Mohindar S. Seehra, Subhash Thota

In spin-glasses (SG), the relaxation time $\tau$ ($=1/2\pi f$) vs. $T_f$ data at the peak position $T_f$ in the temperature variation of the ac magnetic susceptibilities at different fr…
