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…
Anisotropic Magnetocaloric Properties of The Ludwigite Single Crystal Cu2MnBO5
A. G. Gamzatov, Y. S. Koshkidko, D. C. Freitas +5
We present the results of a thorough study of the specific heat and magnetocaloric properties of a ludwigite crystal Cu2MnBO5 over a temperature range of 60 - 350 K and in magnetic…
Magnon excitations and quantum critical behavior of the ferromagnet URuGe
M. P. Nascimento, M. A. Continentino, A. López +8
We present an extensive study of the ferromagnetic heavy fermion compound URuGe. Measurements of electrical resistivity, specific heat and magnetic properties show that…
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…
