Pressurizing strategically selected compositions of the EuCu2(Ge1−xSix )2 series affords an opportunity for gaining microscopic insight into the ground-state properties and interplay between magnetism and valence fluctuations across a quantum critical point. This is investigated…

Increasing Si concentrations in the EuCu2 (Ge1−xSix )2 series tunes the divalent Eu antiferromagnetic (AF) compound EuCu2Ge2 (TN = 14 K) to a nonmagnetic intermediate valence (IV) system EuCu2Si2. There is a collapse of the magnetic state and heavy quasiparticles occur at x ∼ 0.7…

Pure EuC2, free of EuO impurities, was obtained by the reaction of elemental europium with graphite at 1673 K. By means of synchrotron powder diffraction experiments, the structural behavior was investigated in the temperature range from 10 to 1073 K. In contrast to former result…
