Description

Neutron elastic scattering experiments have been carried out on the spin gap system TlCuCl3 in magnetic fields parallel to the b-axis. The magnetic Bragg peaks indicative of the field-induced Neel ordering were observed for magnetic field H > Hg approx. = 5.6 T in the a* - c* plane. The spin structure in the ordered phase was determined and the transverse spin ordering was confirmed. The Bragg peak intensities were measured as a function of temperature and magnetic field. The present result are discussed in connection with a theory of the Bose-Einstein condensation of magnons. (author)
