The influence of external fluctuations in phase separation processes is analysed. These fluctuations
arise from random variations of an external control parameter. A linear stability analysis of the
homogeneous state shows that phase separation dynamics can be induced by external noise. The
spatial structure of the noise is found to have a relevant role in this phenomenon. Numerical
simulations confirm these results. A comparison with order-disorder noise induced phase transitions
is also made.
