The equilibrium conformations of a flexible permanent magnetic filament that consists sequence linked colloidal nanoparticles with short-ranged Lennard-Jones attractive interactions (Stockmayer polymer) are thoroughly analysed via Langevin dynamics simulations. A tentative phase diagram is presented for chain length N = 100. exhibits several unusual conformational phases when compared to non-magnetic chains. These characterised by large degree anisotropy, and consist closed chains, helicoidal-like states, partially collapsed very compact disordered states. contains interesting features like the existence at least two 'triple points'.
