Description
We investigate possible intermediate structures in the process of microphase separation in diblock copolymers. By employing the two-mode expansion valid in the weak-segregation regime, we have found that the Fddd structure and diamond structure of interconnected domains can be metastable whereas the hexagonally perforated lamellar structure and FCC structure exist as a saddle point of the free energy landscape and hence these are unstable
