Exposing the spin glass ground state of the non-superconducting LaSrCuZnO high- oxide
C. Panagopoulos, A. P. Petrovic, A. D. Hillier +3
We have studied the spin glass behaviour of non-superconducting LaSrCuZnO (). As in the superconducting analogues of these samples th…
Low-frequency spins and the ground state in high-Tc cuprates
C. Panagopoulos, J. L. Tallon, B. D. Rainford +3
We study the spin fluctuations of pure and Zn-substituted high temperature superconductors (HTS) using the muon spin relaxation (muSR) technique. Superconductivity is found to coex…
Evidence for a generic novel quantum transition in high-Tc cuprates
C. Panagopoulos, J. L. Tallon, B. D. Rainford +3
We study the low-energy spin fluctuations and superfluid density of a series of pure and Zn-substituted high- superconductors (HTS) using the muon spin relaxation and -sus…
Penetration Depth Measurements in MgB_2: Evidence for Unconventional Superconductivity
C. Panagopoulos, B. D. Rainford, T. Xiang +3
We have measured the magnetic penetration depth of the recently discovered binary superconductor MgB_2 using muon spin rotation and low field -susceptibility. From the damping…
Antiferromagnetic Correlations versus Superfluid Density in La_{2-x}Sr_xCuO_4
C. Panagopoulos, B. D. Rainford, J. R. Cooper +1
We have performed muon spin relaxation and low field ac-susceptibility measurements in a series of high quality samples of La_{2-x}Sr_xCuO_4 (x=0.08-0.24) as a function of temperat…
