| Abstract: | The temperature dependence of the order parameter (〈M
2〉, the mean-square spin excess per spin) for a system with a finite number of spins of the 1D Ising model was investigated.
It was shown that there is a nonzero temperature T
s below which 〈M
2〉 rapidly tends to unity. The analogy between the 1D ensemble of a finite number of spins and a system of superparamagnetic
particles is discussed. |
