Wetting diagram for paranematic wetting when t = 0.1500 ( T = 308.46 K) is approached from below, in the parameter space of the surface potential: reduced magnetic field h versus the modulus of the quartic coupling strength − η for S s = −0.3, γ = 0.05 ( W 1 = 1.160 × 10−8 J·cm−2), and D = 10 of the system (a) without quartic coupling and (b) with quartic coupling.
