Magnetic Phase Transition and Magnetization Plateau in Cs2CuBr4

The crystal structure of Cs2CuBr4 is the same as that of Cs2CuCl4, which has been characterized as a spin1 2 quasi-two-dimensional frustrated system. The magnetic properties of Cs2CuBr4 were investigated by magnetization and specific heat measurements. The phase transition at zero magnetic field was detected at TN = 1.4 K. It was observed that the magnetization curve has a plateau at about one-...

Monte Carlo study of half–magnetization plateau and magnetic phase diagram in pyrochlore antiferromagnetic Heisenberg model

The antiferromagnetic Heisenberg model on a pyrochlore lattice under external magnetic field is studied by classical Monte Carlo simulation. The model includes bilinear and biquadratic interactions; the latter effectively describes the coupling to lattice distortions. The magnetization process shows a half–magnetization plateau at low temperatures, accompanied with strong suppression of the mag...

Magnetic Structure and Phase Diagram of TmB4

Magnetic structure of single crystalline TmB4 has been studied by magnetization, magnetoresistivity, and specific heat measurements. A complex phase diagram with different antiferromagnetic phases was observed below TN1 = 11.7 K. Besides the plateau at half-saturated magnetization (1/2 MS), also plateaus at 1/9, 1/8 and 1/7 of MS were observed as a function of applied magnetic field B ‖ c. From...

Magnetic-field induced isotropic to nematic liquid crystal phase transition.

We report on measurements of magnetic-field induced nematic order in the bent-core liquid crystal 4-chlororesorcinol bis[4-(4-n-dodecyloxybenzoyloxy) benzoate]. Using the 31 T solenoid at the National High Magnetic Field Laboratory, we have observed, at temperatures less than 1 degrees above the clearing point, a first-order transition to the nematic phase. The critical magnetic field at which ...
