Nowadays, the magnetic materials with special functional characteristics are played very
important roles in the development of our present modern society. The magnetic …

This review is an up-to-date snapshot of the current situation in studies of materials with
competing electron spectrum instabilities, namely Cooper pairing, on the one hand, and …

The interaction of rare-earth magnetism and superconductivity has been a topic of interest
for many years. In classical magnetic superconductors (Chevrel phases, ternary rhodium …

Abstract Superconducting [(Li1− xFex) OH](Fe1− yLiy) Se (x≈ 0.2, y≈ 0.08) was
synthesized by hydrothermal methods and characterized by single‐crystal and powder X …

This review deals with the properties of superconductors with competing electron spectrum
instabilities, namely, charge-density waves (CDWs) and spin-density waves (SDWs). The …

Neutron diffraction has been used to study the magnetic order in RuSr 2 GdCu 2 O 8. The
Ru moments order antiferromagnetically at TN= 136 (2) K, coincident with the previously …

The magnetic structure of the heavy fermion antiferromagnet CeRhIn 5 is determined using
neutron diffraction. We find a magnetic wave vector q M=(1/2, 1/2, 0. 2 9 7), which is …

The concept of the Fermi surface is at the very heart of our understanding of the metallic
state. Displaying intricate and often complicated shapes, the Fermi surfaces of real metals …

We report the measurements of the anisotropic magnetization and magnetoresistance (MR)
on single crystals of EuFe 2 As 2, a parent compound of ferro-arsenide high-temperature …

An understanding of the effects of electronic correlations in quantum systems is one of the
most challenging problems in physics, partly due to the relevance in modern high …
