The nuclear quadrupole interaction of Ta-181 in the intermetallic compound Hf2Rh
(Journal of Physics: Condensed Matter, 1999)
The time differential perturbed angular correlation technique has been used to measure the electric field gradient at Ta-181 impurities in the intermetallic compound Hf2Rh. The results of the measurements show the presence ...
Soliton-induced modification of the speed of sound in quasi-one-dimensional molecular crystals
(Journal of Physics: Condensed Matter, 1998)
The influence of the anharmonic vibron-phonon coupling, arising on account of a dressing effect, on the characteristics of the lattice subsystem in quasi-one-dimensional molecular crystals was examined within the pseudo-harmonic ...
Quantum well shape tailoring via inverse spectral theory: optimizing resonant second-harmonic generation
(Journal of Physics: Condensed Matter, 1998)
A procedure for the design of quantum well structures optimized as regards intersubband double-resonant second-harmonic generation is proposed. It relies on the inverse spectral theory, allowing one to start from an arbitrary ...
Electronic structure and electric field gradient calculations for Hf2Fe intermetallic compounds
(Journal of Physics: Condensed Matter, 1999)
Using the first-principles full-potential linear muffin-tin orbital method in the atomic sphere approximation, we have calculated the electronic structure of the intermetallic compound Hf2Fe, and evaluated the electric ...
Investigation of the compound Hf2Ni: the electronic structure and the electric field gradient
(Journal of Physics: Condensed Matter, 1998)
The electronic structure and electric field gradient (EFG) of the intermetallic compound Hf2Ni are calculated on the basis of a recently developed first-principles band-structure full-potential (FP) linear-muffin-tin-orbital ...
Magnetic moments of transition metals overlayers on fcc Ni surface
(Journal of Physics: Condensed Matter, 1998)
We calculate the magnetization profile in the (111) surface of face-centred cubic (fcc) Ni covered by a monolayer or a bilayer of 3d and 4d transition metals. The observed trends can be explained as in earlier works in ...
