Structural and spectroscopic investigation of the charge-ordered, short-range ordered, and disordered phases of the CoOBO ludwigite
C. W. Galdino, D. C. Freitas, C. P. C. Medrano +13
In this work, we investigate the representative case of the homometallic Co ludwigite CoCoOBO ( space group) with four distinct Co crystallographic si…
Iron-based superconductivity extended to the novel silicide LaFeSiH
F. Bernardini, G. Garbarino, A. Sulpice +6
We report the synthesis and characterization of the novel silicide LaFeSiH displaying superconductivity with onset at 11 K. We find that this pnictogen-free compound is isostructur…
Strong enhancement of superconductivity at high pressures within the charge-density-wave states of 2H-TaS 2 and 2H-TaSe 2
D. C. Freitas, P Rodiere, M. R. Osorio +9
We present measurements of the superconducting and charge density wave critical temperatures (Tc and TCDW) as a function of pressure in the transition metal dichalchogenides 2H-TaS…
Charge order and suppression of superconductivity in HgBa2CuO4 at high pressures
Manuel Izquierdo, Daniele C. Freitas, Dorothée Colson +9
New insight into the superconducting properties of HgBa2CuO4 (Hg-1201) cuprates is provided by combined measurements of the electrical resistivity and single crystal X-ray diffract…
Experimental consequences at high temperatures of quantum critical points
D. C. Freitas, P. Rodière, M. Núñez +4
We study the Cr_(1-x) Re_x phase diagram finding that its phase transition temperature towards an antiferromagnetic order T_N follows a quantum [(x_c-x)/x_c ]^ψ law, with ψ=1/2, fr…
Electronic structure and Fermi surface tolopogy of NaCoO
A. Bourgeois, A. A. Aligia, T. Kroll +1
We construct an effective Hamiltonian for the motion of T2g highly correlated states in NaxCoO2. We solve exactly a multiband model in a CoO6 cluster with electronic occupation cor…
