We present initial results of investigation of influence of impurities on magnetic properties of lanthanides intermetallic compounds. We study impurity effect on the REPd2T3 hexagonal compounds which are interesting for various types of magnetic ordering and other effects such as heavy-fermion behavior. In the first stage we studied Pr compounds, which are reported to be nonmagnetic due to crys...

Intermetallic compounds (IMCs) play a great role in solder joint reliability. Intermetallic formation was studied between SnAgSb solder and Cu substrate of a power package device. The integrity of IMC region is vital to the performance and reliability of the semiconductor packages. The solder joint of the as received packages were subjected to the thermal aging test for 50, 100, 200 and 400 hou...

We are applying perturbed angular correlations (PAC) to study point defects near 111In probes in ordered B2 alloys. Systems studied include NiAl, CoAl, FeAl, CoGa and PdIn Ten different point defect configurations have been observed in annealed, quenched or mechanically-milled samples. The present status of this work is summarized. Systematics of hyperfine interactions of vacancy defects are th...

based on the crystal and magnetic structural properties of some gd intermetallic compounds, it is shown that with increasing conduction electron concentration, gd experiences electronic and magnetic instability, and that these behaviors point to the appearance of kondo lattice. we suggest that the conduction electrons have gained local character. it is shown that kondo effect should be observed...
