Gaussian, three-dimensional-xy, and lowest-landau-level scalings in the low-field fluctuation magnetoconductivity of bi/sub 2/ sr/sub 2/ cacu/sub 2/ o/sub 8/
(1997) [Journal article]Systematic measurements of low-field fluctuation magnetoconductivity in a single crystal of Bi2Sr2CaCu2O8 are reported. Gaussian, critical, and lowest-Landau-level scalings are observed. In the Gaussian regimes, large ... -
Specific heat and magnetic order in LaMnO/sub 3+[delta]/
(1999) [Journal article]Magnetic and specific-heat measurements are performed in three different samples of LaMnO₃₊[delta], with δ = 0.11, 0.15, and 0.26, presenting important disorder effects, such as carrier localization, due to high amounts ... -
Structural and spectroscopic investigation of the charge-ordered, short-range ordered, and disordered phases of the Co3O2BO3 ludwigite
(2021) [Journal article]Charge ordering is prone to occur in crystalline materials with mixed-valence ions. It is presumably accompanied by a structural phase transition, with possible exceptions in compounds that already present more than one ...
