Pressure Induced Quantum Phase Transitions in Metallics Oxides and Pnictides
… points are approached by applying hydrostatic pressure in two different compounds namely Eu2Ir22O 7 and FeCrAs. The former is a ternary metal oxide and the latter is a ternary metal pnictide. A major component of this work was the development of the ultra-high pressure measurements by means of …

Superconductivity in the proximity of a quantum critical point
… is a uniaxial 4f ferromagnet, where physical pressure or a transverse field may be used to tune the magnetic transition towards T = 0 K. Our investigations, however, did not reveal the presence of superconductivity. It is likely that the field tuned transition does not correspond to a true …

Investigation of the magnetic and magnetocaloric properties of complex lanthanide oxides
… of the magnetic ion as well as variations in the chemical pressure radically alters the nature of magnetic ordering, the degree of frustration and the magnetocaloric performance. In the second part, the garnets $Ln_3A$Ga$_4$O$_{12}$, $Ln$ = Gd, Tb, Dy, Ho, $A$ = Cr, Mn, are studied. Introducing …

Transport and thermodynamic studies of the superconductors A3T4Sn13 and YFe2Ge2
… be suppressed to zero by tuning with physical or chemical pressure. In (Ca$_x$Sr$_{1−x}$)$_3$Rh$_4$Sn$_13$, the quantum critical point can be accessed purely by chemical substitution at x ~ 0.9. In the vicinity of the QCP, we expect large fluctuations of the order parameter at low temperatures, …

Theoretical studies of structural and electronic properties in transition metal oxides
… the size of the rare earth ions, often known as chemical pressure, and the stability of the coherent Jahn-Teller distortions in undoped perovskite manganites. Using a Keating model expressed in terms of atomic scale symmetry modes, it is shown that there exists a coupling between the uniform …

Chemical pressures in crystalline solids
… equation in crystalline systems and the chemical bond. The crystal of Cs2UO2Cl4 has been used with the double objective to advance in the understanding of its behavior under hydrostatic pressure solving certain controversies in relation to the rule of Badger and to know the computational …

Chemical crystallography at the interface of physics, chemistry, and in engineering: structure determination of highly correlated extended solids, main group compounds, coordination complexes, and bioceramics
… (Yb2Pd3Ga9), determining the influence of chemical doping on structure and physical properties (P-, Yb-, Co-, and Cu-doping of CaFe4As3 and Mn-doping of Sr3Ru2O7), elucidating the structure of transition metal corrole complexes to understand its regioselectivity of various substituents and …
