We report a new type of thermal nonlinear media (m-cresol/nylon solutions) that exhibits a giant tunable self-defocusing nonlinearity. The measured Kerr coefficient in such thermal nonlinear solutions is orders of magnitude higher than that of most previously known thermal materials. In addition, we demonstrate the generation of dark spatial solitons in these isotropic nonlocal nonlinear media, and observe to our knowledge the strongest effect of dark-soliton attraction ever reported in thermal defocusing media.
