Description

Under the hydrostatic pressure P = 1.48 GPa, polarized neutron elastic scattering experiments have been carried out on the coupled spin dimer system TlCuCl3 with the gapped ground state at ambient pressure. Pressure-induced magnetic ordering occurs at the transition temperature TN = 16.9 K. As in the field-induced and impurity-induced magnetic ordered phases, the ordered moments lie in the a-c plane just below TN. An additional spin reorientation (SR) phase transition was observed at TSR = 10K, where the ordered moments start to incline toward the b-axis. The temperature variations of the direction and the magnitude of the ordered moments were also investigated. (author)
