We analyze a phase-field system where the energy balance equation is linearly coupled with a nonlinear and nonlocal ODE for the order parameter . The latter equation is characterized by a space convolution term which models long-range interactions and a singular configuration potential that forces to take values in the interval (􀀀1; 1). We prove that the corresponding dynamical system is dissipative, i.e., it has a bounded absorbing set in a suitable phase space. Then we establish the existence of a finite-dimensional global attractor.
