Magnetic field-induced ordering in SrDy2O4.
Heat capacity measurements were used to investigate the magnetic ordering processes in single-crystal samples of SrDy2O4 in a magnetic field applied along the [010] and [001] directions. In zero field this compound appears to be magnetically disordered down to at least 0.39 K. A magnetic field applied along the [010] direction induces a very sharp transition at 20 kOe, seen as a strong peak in ...

متن کاملMagnetic Field Induced Ordering in Quasi-One-Dimensional Quantum Magnets
Three-dimensional magnetic ordering transitions are studied theoretically in strongly anisotropic quantum magnets. An external magnetic field can drive quasi-one-dimensional subsystems with a spin gap into a gapless regime, thus inducing long-range three-dimensional magnetic ordering due to weak residual magnetic coupling between the subsystems. Compounds with higher spin degrees of freedom, su...
متن کاملShear- and magnetic-field-induced ordering in magnetic nanoparticle dispersion from small-angle neutron scattering.
Small-angle neutron scattering experiments have been performed to investigate orientational ordering of a dispersion of rod-shaped ferromagnetic nanoparticles under the influence of shear flow and static magnetic field. In this experiment, the flow and flow gradient directions are perpendicular to the direction of the applied magnetic field. The scattering intensity is isotropic in zero-shear-r...
متن کاملSpecific Heat Study of the Field-Induced Magnetic Ordering in the Spin Gap System TlCuCl3
Specific heat measurements have been performed in the coupled dimer system TlCuCl3, which has a singlet ground state with the excitation gap ∆ ≃ 7.5K. The cusplike anomaly indicative of the 3D magnetic ordering was clearly observed in magnetic fields higher than the critical field Hg corresponding to the gap ∆. The phase boundary determined by the present specific heat measurements coincides wi...
