An experimental investigation of the surface tension temperature dependence σ(T) of the condensed phase (drop-like aggregates) in magnetic fluids undergoing magnetocontrollable phase transition of gas-liquid type was carried out. Accurate numerical processing of experimental data has revealed an anomalous (if compared to ordinary fluids) behavior of the σ(T) function for all tested samples: it enhances with the growth of temperature due to the granulometric aspect of the first-order phase transition in magnetic fluids. Figs 3, Refs 6.
