The Magnetic Field

A high magnetic field is a useful tool to control the crystal alignment of ceramic materials. In this study, a horizontal 10T static magnetic field was imposed on slurry containing hydroxyapatite (HAp) crystals under the horizontal mold rotation during slip casting process so as to introduce uni-axial alignment for some amount of crystals in the sample, and then it was sintered in atmosphere without the magnetic field. From X-ray diffraction, it has been found that the HAp crystals in the sample treated with the mold rotation under the magnetic field were aligned its c-axis to a particular direction.

Helmholtz Coils

Magnetic fields obtained by discharging a large capacitor bank through Helmholtz coils can be produced in excess of 25 T for relatively short periods of time, ~ 1 msec and longer. When combined with modern facilities for diffraction at modern neutron and synchrotron x-ray sources, one can study the structure and phase diagrams of new materials under extremes of magnetic field. I will present two such studies, each focussing on a new magnetic material which exhibit exotic low temperature states. I will show time-resolved neutron Laue diffraction on the multiferroic magnet MnWO4 [1], and time-resolved synchrotron x-ray studies of large magneto-elastic effects in the geometrically-frustarted pyrochlore magnet Tb2Ti2O7 [2], both in magnetic fields up to ~ 30 T. Such studies of new materials in extreme sample environments can be very revealing as to the nature of their exotic low temperature states.

ABSTRACTWe have measured the anisotropy of the electron diffusivity in a series of Cu/Al multilayers. The Samples were made by magnetron sputtering and characterized by X-Ray diffraction. The low temperature transverse magnetoresistance of each sample was measured for two different orientations of the magnetic field—parallel and perpendicular to the plane of the sample film. The Weak Localization(WL) contribution to the magnetoresistance is sensitive to the component of the electron diffusivity in a plane perpendicular to the magnetic field. We use this fact to calculate the ratio of different components of the diffusivity from the observed dependence of magnetoresistance on the orientation of magnetic field. For our samples, the ratio of the in and out of plane components of the diffusivity, (Dxy/Dz), is seen to range between 1 and 2.2, and the anisotropy is largest for the sample with the highest conductivity.

Nanometer Al2O3 particles reinforced 7055Al composites were processed by high magnetic field with 2T,3T and 4T magnetic induced intensity (B) with constant 30 pulses. Transmission Electronic Microscopy (TEM) and X ray diffraction (XRD) were mainly used to analyze some characteristic of the treated samples. The results show that with the increase of B the dislocation density was enhanced apparently. It is deduced that plastic deformation was the main reason of high density dislocation. The magnetoplasticity effect was the source of plastic deformation.
