Magnetic and Charge Fluctuations in High-$T_c$ Superconductors

H. A. Mook, F. Dogan, B. C. Chakoumakos

Neutron scattering has been used to study the spin fluctuations in the YBa${}_2$Cu${}_3$O${}_{7-x}$ and Bi${}_2$Sr${}_2$CaCu${}_2$O${}_8$ materials. Evidence is found for both incommensurate flu…
