Phase decomposition in amorphous Cu12.5Ni10Zr411Ti14Be22.5 alloy as annealed in the super-cooled liquid range was studied by applying small angle neutron scattering (SANS). As annealed between 600 K and 700 K, the alloy was observed to decompose into two new amorphous phases,with the second phase precipitates embedded in the matrix of the first. Long time annealing of the alloy results in crystallization in addition to evolution of the decomposed *** kinetic diagram of the decomposition and crystallization for this alloy is given. The second phase precipitates have several nanometers in size and occupy a quite low volume fraction. The decomposition of the supercooled liquid in overall temperature range exhibits the features of spinodal reaction.

A modified Monte-Carlo(MC) method to simulate the regular growth of binary eutectic alloys is presented. It is found that the growth rate has a linear dependence on the chemical potential difference between the solid and liquid; the relation between the lamellar spacing A and growth rate R accords well with the prediction of Jackson-Hunt(JH) theory unless the growth rate is very low.

The spin-dependent intedecial tunneling and the corresponding tunnef-type magnetoresistance (TMR) have been observed in granular perovskite La_(1-x)Sr_xMnO_3 with x from 0.05 to *** shows that the intedecial tunneling originates from the magnetic difference between thegrain core and the sudece, and the TMR stems from the field-induced change of magnetic orderin the interface.

SPUTTER-DEPOSITED NiTi thin films are becoming more and more important because of their po-tential applications to the intelligent thin-film systems. The as-deposited NiTi thin films pre-pared by magnetron sputtering are generally amorphous. Because the amorphous NiTi thinfilms cannot show shape memory effect, they should be crystallized under appropriate anneal-

The degradation behavior of SrBi2Ta2O9 (SBT) thin films annealed in forming gas (5%H2+95%N2) was investigated. The ferroelectric remnant polarization Px of SBT had a severe decrease in the containing H2 atmosphere at 400°C. SEM results showed that Bi could be reduced from SBT thin films for the effect of H2. The reduction role increased with a rise of annealing temperature. SBT thin films lost their ferroelectricity when the annealing temperature was above 450°C. It implied that the degradation of Pr value or the disappearance of ferroelectricity in SBT thin, films had the relationship with the reductive amounts of Bi in SBT. H2 played an important role in degradation of ferroelectric SBT thin films. This role could be attributed to its strong reduction activity during forming gas annealing.
