Neutron diffraction is used to investigate the field-induced,antiferromagnetically ordered state in the two-leg spin-ladder material(Hpip)2CuBr4. This "classical" phase, a consequence of weak interladdercoupling, is nevertheless highly unconventional: its properties are influencedstrongly by the spin Luttinger-liquid state of the ladder subunits. Wedetermine directly the order parameter (transverse magnetization), the orderingtemperature, the spin structure, and the critical exponents around thetransition. We introduce a minimal, microscopic model for the interladdercoupling and calculate the quantum fluctuation corrections to the mean-fieldinteraction.
