Anisotropic superconducting properties of aligned Sm$_{0.95}$La$_{0.05}$FeAsO$_{0.85}$F$_{0.15}$ microcrystalline powder (2008)

Chang, B. C., Hsu, C. H., Hsu, Y. Y., Wei, Z., Ruan, K. Q., Li, X. G., ...

The Sm$_{0.95}$La$_{0.05}$FeAsO$_{0.85}$F$_{0.15}$ compound is a quasi-2D layered superconductor with a superconducting transition temperature T$_c$ = 52 K. Due to the Fe spin-orbital related...

Studies of Effects of Current on Exchange-Bias: A Brief Review (2008)

Bass, J., Sharma, A., Wei, Z., Tsoi, M.

MacDonald and co-workers recently predicted that high current densities could affect the magnetic order of antiferromagnetic (AFM) multilayers, in ways similar to those that occur in ferromagnetic...

Economic simplex optimisation for broad range property prediction: Strengths and weaknesses of an automated approach for tailoring of parameters (2008)

Müller, T.J., Roy, S., Wei, Z., Maaß, A., Reith, D.

The need for predicting physical compound properties supplementing experimental data is considerable. Nowadays a wide range of classical simulation techniques is available for computing a multitude...

Current-Induced Magnetoresistance in Antiferromagnetic Spin Valves (2007)

Wei, Z., Sharma, A., Bass, J., Tsoi, M.

This paper has been withdrawn. The results of measurements on new samples of different types call into question our explanation in the original version of the paper. A revised version will appear...

Surface chemistry of nanoscale Fe3O4 dispersed in magnetic fluids (2007)

JianHan, X., Hui, S., Wei, Z., Yi, L., JiaXin, D., Günther, B.

The interaction between stabilizers and nanoparticles is one of the important factors to prepare stable magnetic fluids. The magnetic nano-size Fe3O4 core with single domain and the average grain...

Convergence Analysis of Some Methods for Minimizing a Nonsmooth Convex Function (1998)

Birge, J. R., Qi, L., Wei, Z.

In this paper, we analyze a class of methods for minimizing a proper lower semicontinuous extended-valued convex function . Instead of the original objective function f , we employ a convex...

A General Approach to Convergence Properties of Some Methods for Nonsmooth Convex Optimization (1998)

Birge, J. R., Wei, Z., Qi, L.

Based on the notion of the ε -subgradient, we present a unified technique to establish convergence properties of several methods for nonsmooth convex minimization problems. Starting from the...

All-solid-state cavity-dumped sub-5-fs laser (1997)

Baltuška, A., Wei, Z., Pshenichnikov, M.S., Wiersma, D.A., Szipőcs, Róbert

We discuss in detail a compact all-solid-state laser delivering sub-5-fs, 2-MW pulses at repetition rates up to 1 MHz. The shortest pulse generated thus far measures only 4.6 fs. The laser system...
