Abstract
The magnetic spectra χ″ of YBa2Cu3O 6.5 are compared with calculated results by the expression χ(q, ω) = χ0(q, ω) / {1 + J(q)χ0(q, ω)} with J(q) = J(cos qxa + cos qya). For the proper band parameters and other parameters, we obtained satisfactory agreement between experimental and calculated results without considering dynamical "stripes". The quasi particle broadening has been found to suppress the antiferromagnetic ordering. Effects of the dynamical "stripes" on χ″(q, ω) are clearly visible in La2-xSr xCuO4, which is in clear contrast to the results of YBa2Cu3O6.5.
