WebFinally, we show that interactions between colloids, mediated by neutral non-grafted polymers, generally follow the trend: attraction ⇒ repulsion (or vanishing interaction) ⇒ attraction as the surface affinity toward monomers proceeds from repulsive to attractive. WebS/F bilayers. For these structures a non-monotonic behaviour of the critical temperature, Tc, over ˘F as a function of the thickness of the ferromagnetic layer, dF, has been found theoretically as well as experimentally [1,15–20]. The superconducting transition temperature is the simplest parameter which reveals intriguing behaviour typical of
