Abstract.

The orientation of dimyristoylphosphatidylcholine (DMPC) multilamellar vesicles below and close to the main phase transition and of DMPC/C12E8 mixed micelles in strong magnetic fields has been studied via small-angle neutron scattering at magnetic fields of 1–4 T. A partial deformation of the DMPC vesicles from spherical to ellipsoidal shape was observed even at low magnetic field (H=2 T). The orientation of the polymer-like mixed micelles of DMPC/C12E8 in the magnetic field shows a Gaussian-coil behavior independent of the applied magnetic field strength.
