The techniques most often used to determine components of the third-order susceptibility, x(3), include degenerate four-wave mixing, 1 nearly degenerate threeand four-wave mixing, 2 ellipse rotation, 3 optical third-harmonic generation,4 photoacoustics,5 beam-distortion methods,6 8 and nonlinear transmission.9 Some of these have been adapted to measure the anisotropy of x<a) .2•5•6•9 We introdu...

Azimuthal distributions of particles produced in nucleus-nucleus collisions are measured with respect to an estimated reaction plane which, because of finite multiplicity fluctuations, differs in general from the true reaction plane. It follows that the measured distributions do not coincide with the true ones. I propose a general method of reconstructing the Fourier coefficients of the true az...

Which range of structures contributes to light scattering in a continuous random media, such as biological tissue? In this Letter, we present a model to study the structural length-scale sensitivity of scattering in continuous random media under the Born approximation. The scattering coefficient μs, backscattering coefficient μb, anisotropy factor g, and reduced scattering coefficient μs* as we...

It was recently recognized that the internal structure of scatterers can significantly alter the picture of wave propagation and localization in random media. When the size of scatterers cannot be neglected, scattering is anisotropic and a ‘‘dwell time’’ for waves appears in addition to the time of flight between scattering. This substantially modifies such parameters describing wave propagatio...

We report the experimental observation of room-temperature perpendicular magnetic anisotropy ~PMA! in Ni/Pd ~111! multilayer films having the thickness range of 5–11 Å Ni and 4–11 Å Pd sublayers, prepared by direct current magnetron sputtering on glass substrates at Ar sputtering pressure of 7 mTorr. Perpendicular magnetic anisotropy was found to be sensitively dependent on both Niand Pd-sublay...

We have studied the easy-axis reorientation of Ni/Pd multilayer with varying Ar sputtering pressure. All the Ni/Pd multilayers prepared by dc-magnetron sputtering at an Ar sputtering pressure of 2 mTorr show in-plane magnetic anisotropy. However, room-temperature perpendicular magnetic anisotropy was observed in Ni/Pd multilayers prepared at an Ar sputtering pressure of 7 mTorr. To understand t...

Transport measurements (electrical resistivity, Seebeck coefficient, and thermal conductivity) in the temperature range 80–500 K are presented for single crystals of the quasi-one-dimensional (Q1D) semiconductor Li0.33MoO3. Opposite signs are observed for the Seebeck coefficient along the trinclinic a and c axes, with Sc Sa ’ 250 lV/K near room temperature and ’100 lV/K at 380 K. The thermal co...
