We have studied the temperature dependence of the upper critical fields μ 0 H c 2 of K x Fe 2 - y Se 2 - z S z single crystals up to 60 T. The μ 0 H c 2 for H ∥ a b and H ∥ c decrease with increasing sulfur content. The detailed analysis using Werthamer-Helfand-Hohenberg theory including the Pauli spin-paramagnetic effect shows that μ 0 H c 2 for H ∥ a b is dominated by the spin-paramagnetic effect, which diminishes with higher S content, whereas μ 0 H c 2 for H ∥ c shows a linear temperature dependence with an upturn at high fields. The latter observation can be ascribed to multiband effects that become weaker for higher S content. This results in an enhanced anisotropy of μ 0 H c 2 for high S content due to the different trends of the spin-paramagnetic and multiband effect for H ∥ a b and H ∥ c , respectively.
