Titanocene derivatives containing titanium–carbon σ-bonds

Abstract

The Monte Carlo technique is used to calculate the order parameter, e, of the four-dimensional spin-: Ising ferromagnet in a simple hypercubic lattice. The orderparameter data are described by @(r) =B(-r)1'211n(-r)l"3[l +Q ln~ln(-t)///ln(-r)/] in the range 0.01s-r =(T,-T)/Tc<0.56 with parameters B =1.543*0.002 and Q = -0.030*0.02. The form of @(t) agrees with that predicted by renormalisation group theory.
