Popis:	Nonfunctionalized n-alkanes, a basic organic building block, are not commonly associated with magnetic behavior. To quantify magnetic field effects on wax crystals, synchrotron x-ray scattering was used to measure the angular distribution arising from competition between Brownian rotation and magnetic energy in a dispersion of uniform-sized n-alkane single crystals. Dramatic alignment of both axes occurred with a preference of the carbon-backbone plane to be {perpendicular} to {rvec H}. Diamagnetic anisotropies were obtained by quantitative analysis of the orientational distribution. {copyright} {ital 1998} {ital The American Physical Society}
