The field induced magnetic phase transitions of Cs2CuBr4 were investigated by means of magnetization process and neutron scattering experiments. This system undergoes magnetic phase transition at Neél temperature TN = 1.4K at zero field, and exhibits the magnetization plateau at approximately one third of the saturation magnetization for the field directions H ‖ b and H ‖ c. In the present stud...

The effects of nanostructuration on the magneto-optic properties of ultrathin monocrystalline iron films grown on MgO ~001! are investigated through the magneto-optic coefficients, which have a linear and quadratic dependence on the magnetization. The photon energy dependence of such magneto-optic coefficients is determined by measuring the relative variations of the reflectivity (DRpp /Rpp) fo...

Magnetization measurements with the magnetic field parallel to the c-axis were performed on overdoped Bi2¡ xPbxSr2CaCu2O8+ ± single crystals. Different from undoped Bi2Sr2CaCu2O8+ ± single crystal, a pronounced anomalous peak with maximum peak field over 5000 G can be observed in enlarging temperature window from 0.2Tc to 0.9Tc; both the anomalous magnetization peak H2p and the sharp onset of t...

Surface-sensitive second-harmonic generation, with the proper choice of symmetry, has demonstrated an extremely high sensitivity for detecting surface magnetization on Si(111)-7×7 induced by an external magnetic field of 10 T. Electron spins at the dangling bonds are suggested to be responsible for the observed magnetization of surfaces of nonmagnetic semiconductors. The temperature dependence ...

In this paper, we propose the method to analyze the magnetization distribution in magnetoanisotropic materials by using the finite-element method considering the improved variable magnetization and Stoner–Wohlfarth model. By using this method, furthermore, the effect of the eddy currents induced in permanent magnets was analyzed. From the analyzed result, it is clarified how the magnetization d...

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-...
