Magnetism in a charge doped cuprate chain
We have recently succeeded in measuring the excitation spectrum of charge doped cuprate chains with a 90 degree Cu-O-Cu bonding geometry. This study resolved a long standing... -
A Neutron Diffraction study of the novel layered cuprate IrSr2154Sm1.15Ce0.85...
We have synthesised a novel material IrSr2Sm1.15Ce0.85Cu2O10 . Preliminary magnetic measurements evidence two magnetic transitions at Tc = 125 K and TM2= 6 K. Above Tc however... -
Unravelling spin fluctuation components in a stripe-ordered cuprate
In previous experiments at ILL we observed a gap in the magnetic excitation spectrum of the stripe-ordered superconductor (La,Nd)2-xSrxCuO4, x=0.12. We observed a spin gap of... -
A muSR spectroscopic study of the spin dynamics and reentrant spin-glass tran...
We have recently synthesised the novel iridocuprate IrSr2Sm1.15Ce0.85Cu2O10. This material exhibits a complex temperature dependence of the magnetic susceptibility with multiple... -
The mechanism of cuprate superconductivity investigated in CLBLCO single crys...
Although high quality single crystals of cuprate superconductors have been available for quite some time, comparing the properties of different crystals often raised more... -
Temperature dependence on mangetic excitations from the high Tc cuprate BSCCO
We plan to continue inelastic neutron scattering measurements on the high Tc cuprate superconductor BSCCO with optimum doping. In the proposed experiment, we will have about 40... -
Spin excitations in the pseudogap region of YBCO6.5 Ortho-II Superconductor
We propose to investigate the spin dynamics in the Ortho-II order YBCO6.5 superconductor at energies above 100 meV. This study will be aimed at searching for the broadening of... -
Origin of spin excitation in single-layer cuprate Bi2201
We propose a measurement of spin excitation in heavily underdoped Bi2201 at MERLIN with intent to elucidate an origin of "hourglass" excitation in hole-doped cuprates. Recent...
