Abstract

We check the existence of a spontaneous magnetisation of Ising and Potts spins on semi-directed Barabasi-Albert networks by Monte Carlo simula- tions. We verified that the magnetisation for different temperatures T decays after a characteristic time � (T), which we extrapolate to diverge at positive tem- peratures Tc(N) by a Vogel-Fulcher law, with Tc(N) increasing logarithmically with network size N.
