Non-Gaussian Noise in the In-Plane Transport of Lightly Doped La_{2-x}Sr_{x}CuO_4: Evidence for a Collective State of Charge Clusters
I. Raičević, Dragana Popović, C. Panagopoulos +1
A study of the in-plane resistance noise on a high quality single crystal of La_{1.97}Sr_{0.03}CuO_{4} deep inside the spin-glass phase reveals the onset of non-Gaussianity and the…
Skyrmions in a Doped Antiferromagnet
I. Raicevic, Dragana Popovic, C. Panagopoulos +4
Magnetization and magnetoresistance have been measured in insulating antiferromagnetic La_{2}Cu_{0.97}Li_{0.03}O_{4} over a wide range of temperatures, magnetic fields, and field o…
Large Positive Magnetoresistance of the Lightly Doped La_{2}CuO_{4} Mott Insulator
I. Raicevic, Dragana Popovic, C. Panagopoulos +1
The in-plane and out-of-plane magnetoresistance (MR) of single crystals of La_2CuO_4, lightly doped (x=0.03) with either Sr (La_{2-x}Sr_xCuO_4) or Li (La_2Cu_{1-x}Li_xO_4), have be…
Upper critical fields and thermally-activated transport of Nd(O_0.7F_0.3)FeAs single crystal
J. Jaroszynski, F. Hunte, L. Balicas +9
We present measurements of the resistivity and the upper critical field H_c2 of Nd(O_0.7F_0.3)FeAs single crystals in strong DC and pulsed magnetic fields up to 45 T and 60 T, resp…
Evidence for Charge Glass-like Behavior in Lightly Doped La_{2-x}Sr_{x}CuO_{4} at Low Temperatures
I. Raicevic, J. Jaroszynski, Dragana Popovic +2
A c-axis magnetotransport and resistance noise study in La_{1.97}Sr_{0.03}CuO_{4} reveals clear signatures of glassiness, such as hysteresis, memory, and slow, correlated dynamics,…
