LaPdIn: superconductivity and lattice properties at ambient and elevated pressures.

Lattice and electronic properties of LaPdIn were studied at ambient and elevated pressures so as to determine features related to a specific atomic coordination without any influence of magnetism. We describe temperature dependences of lattice parameters, heat capacity and electrical resistivity of single-crystalline LaPdIn (s.g.

Impact of isoelectronic substitution and hydrostatic pressure on the quantum critical properties of CeRhSi.

There is an ongoing dispute in the community about the absence of a magnetic quantum critical point (QCP) in the noncentrosymmetric heavy fermion compound CeRhSi. In order to explore this question we prepared single crystals of CeRh(SiGe)with= 0.05 and 0.

Ab initio calculations of the crystal field and phonon dispersions in CePdAl and LaPdAl.

CePdAl crystallizes in the CaBeGe-type tetragonal structure (P4/nmm, 129) and undergoes a phase transition to the orthorhombic Cmme structure at around 13 K. Its inelastic neutron spectra reveal an additional magnetic excitation that was ascribed to electron-phonon interaction leading to a formation of a new quantum quasi-bound vibron state. We present the first-principles calculations of the crystal field excitations and lattice dynamics calculations of the phonon dispersions to compare with the experimental data.

Crystal Structure and Magnetic Properties of Uranium Hydride UH Stabilized as a Thin Film.

A new type of uranium binary hydride, UH, with the CaF crystal structure, was synthesized in a thin-film form using reactive sputter deposition at low temperatures. The material has a grain size of 50-100 nm. The lattice parameter a = (535.

UH-based ferromagnets: new look at an old material.

UH is the first discovered material with ferromagnetism based purely on the 5 electronic states, known for more than half century. Although the U metal is Pauli paramagnet, the reduced 5-5 overlap in compounds allows for moment formation and ordering, typically if the U-U spacing exceeds the Hill limit, i.e.
