Unusual behavior of cuprates explained by heterogeneous charge localization
D. Pelc, P. Popčević, G. Yu +3
The cuprate high-temperature superconductors are among the most intensively studied materials, yet essential questions regarding their principal phases and the transitions between…
Percolative nature of the dc paraconductivity in the cuprate superconductors
Petar Popčević, Damjan Pelc, Yang Tang +7
We present an investigation of the planar direct-current (dc) paraconductivity of the model cuprate material HgBaCuO in the underdoped part of the phase diagram. The si…
Emergence of superconductivity in the cuprates via a universal percolation process
Damjan Pelc, Marija Vučković, Mihael Grbić +5
A pivotal step toward understanding unconventional superconductors would be to decipher how superconductivity emerges from the unusual normal state upon cooling. In the cuprates, t…
17O-NMR Knight shift study of the interplay between superconductivity and pseudogap in (Ca_xLa_{1-x})(Ba_{1.75 - x}La_{0.25 + x})Cu_3O_y
T. Cvitanic, D. Pelc, M. Pozek +2
We report systematic 17O-NMR measurements on the high-Tc cuprate (Ca_xLa_{1-x})(Ba_{1.75 - x}La_{0.25 + x})Cu_3O_y, for four different families (different x). Using Knight shift da…
Temperature range of superconducting fluctuations above T_c in YBa_2Cu_3O_{7-δ} single crystals
M. S. Grbic, M. Pozek, D. Paar +6
Microwave absorption measurements in magnetic fields from zero up to 16 T were used to determine the temperature range of superconducting fluctuations above the superconducting cri…
