Novel Ce magnetism in CeDipnictide and Di‐Ce pnictide structures

Novel Ce magnetism in CeDipnictide and Di‐Ce pnictide structures

Density-functional calculations of the electronic structures and magnetism of the pnictide superconductors BaFeAs2 and BaFeSb2

We investigate the structural, electronic, and magnetic properties of the hypothetical compound BaFePn2 Pn=As and Sb , which is isostructural to the parent compound of the high-temperature superconductor LaFeAsO1−xFx. Using density-functional theory, we show that the Fermi surface, electronic structure, and spin-density wave instability of BaFePn2 are very similar to the Fe-based superconductor...

Epitaxial Ce and the magnetism of single-crystal CeÕNd superlattices

The chemical structure of epitaxial g cerium and the chemical and magnetic structures of cerium/ neodymium superlattices have been studied using x-ray and neutron diffraction techniques. The samples were grown using molecular-beam epitaxy, optimized to yield the desired Ce allotropes. The x-ray measurements show that, in the superlattices, both constituents adopt the dhcp structure and that the...

Magnetism and magnetic structures of PrMn2Ge2-xSix.

The structural and magnetic properties of seven PrMn2Ge2-xSix compounds with Si concentrations in the range x = 0.0-2.0 have been investigated by x-ray diffraction, magnetic (5-350 K), differential scanning calorimetry (300-500 K) and neutron diffraction (3-480 K) measurements. Replacement of Ge by Si leads to a contraction of the unit cell and significant modifications to the magnetic states--...
