Phase diagram of heavy fermion systems
The Meccano of heavy fermion systems is shown on different cases going from anomalous monochalcogenides to cerium intermetallic compounds with special focus on the ideal case of the CeRu2Si2 series. Discussion is made in the frame of the interplay between valence, electronic structure (Fermi surface), and magnetism. The nice tools given by the temperature, the pressure, and the magnetic field a...
متن کاملImprovement of P -V Diagram Measurements
This paper presents how much experimental errors are caused by the characteristics of pressure transducers in P-V measurements. In addition, the accuracy of the balanced pressure valve (the B.P.V.) of a free disc type, which determines the cylinder absolute pressure level, is shown. Namely, the indicated gas work was calculated by the following two methods: (a) Sensitivity method (the calibrate...
متن کاملEquilibrium p-T Phase Diagram of Boron: Experimental Study and Thermodynamic Analysis
Solid-state phase transformations and melting of high-purity crystalline boron have been in situ and ex situ studied at pressures to 20 GPa in the 1500-2500 K temperature range where diffusion processes become fast and lead to formation of thermodynamically stable phases. The equilibrium phase diagram of boron has been constructed based on thermodynamic analysis of experimental and literature d...
متن کاملCalculation of the P-T phase diagram and tendency toward decomposition in equiatomic TiZr alloy.
Electronic, structural and thermodynamic properties of the equiatomic alloy TiZr are calculated within the electron density functional theory and the Debye-Grüneisen model. The calculated values of the lattice parameters a and c/a agree well with the experimental data for the α, ω and β phases. The ω phase is shown to be stable at atmospheric pressure and low temperatures; it remains energetica...
متن کاملNEUTRON DIFFRACTION STUDY OF THE p–T PHASE DIAGRAM FOR ERBIUM
Electrical resistivity measurements performed on a single crystal of erbium as a function of temperature and hydrostatic pressure have provided a preliminary p–T phase diagram. The results have been interpreted in terms of a model for the magnetic structures of Er deduced from neutron diffraction studies at ambient pressure. This model predicted the existence of a magnetic structure with a wave...
