In situ synchrotron small‐angle X‐ray scattering was used to investigate various surfactant/water systems with hexagonal and lamellar structures regarding their structural behaviour upon heating and cooling. Measurements of the non‐ionic surfactant Triton X‐45 (polyethylene glycol 4‐ tert ‐octylphenyl ether) at different surfactant concentrations show an alignment of the lamellar liquid‐crystalline structure close to the wall of the glass capillaries and also a decrease in d ‐spacing following subsequent heating/cooling cycles. Additionally, samples were subjected to a weak magnetic field (0.3–0.7 T) during heating and cooling, but no influence of the magnetic field was observed.
