Spin Fluctuations and the Pseudogap in Organic Superconductors
B. J. Powell, Eddy Yusuf, Ross H. McKenzie
We show that there are strong similarities in the spin lattice relaxation of non-magnetic organic charge transfer salts, and that these similarities can be understood in terms of s…
Vertex Corrections and the Korringa Ratio in Strongly Correlated Electron Materials
Eddy Yusuf, B. J. Powell, Ross H. McKenzie
We show that the Korringa ratio, associated with nuclear magnetic resonance in metals, is unity if vertex corrections for the dynamic spin susceptibility are negligible and the hyp…
Antiferromagnetic Spin Fluctuations in the Metallic Phase of Quasi-Two-Dimensional Organic Superconductors
Eddy Yusuf, B. J. Powell, Ross H. McKenzie
We give a quantitative analysis of the previously published nuclear magnetic resonance (NMR) experiments in the k-(ET)2X family of organic charge transfer salts by using the phenom…
Antiferromagnetic Spin Fluctuations and the Pseudogap in the Paramagnetic Phases of Quasi-Two-Dimensional Organic Superconductors
Eddy Yusuf, B. J. Powell, Ross H. McKenzie
We give a quantitative analysis of the published results of nuclear magnetic resonance (NMR) experiments for k-(ET)2X family of organic charge transfer salts by using the phenomeno…
Dynamics of weakly coupled random antiferromagnetic quantum spin chains
Eddy Yusuf, Kun Yang
We study the low-energy collective excitations and dynamical response functions of weakly coupled random antiferromagnetic spin-1/2 chains. The interchain coupling leads to Neel or…
Spin Waves in Antiferromagnetic Spin Chains with Long Range Interactions
Eddy Yusuf, Anuvrat Joshi, Kun Yang
We study antiferromagnetic spin chains with unfrustrated long-range interactions that decays as a power law with exponent , using the spin wave approximation. We find for suffic…
