Abstract

We have performed neutron scattering measurements on the single crystal of La1.875Ba0.125CuO4 in order to study the melting sequence of stripe correlations. Low-energy incommensurate spin fluctuations clearly are observed around (π,π) at low temperatures and remain even above the stripe ordering temperature of 50 K. However, the peak intensity dramatically degrades toward the structural transition temperature between low-temperature tetragonal and low-temperature orthorhombic phases, Td2, of 60 K. No well-defined signal was observed above T d2. These results suggest that the charge fluctuations, which are closely related with the crystal structure, modify the magnetic correlations as expected from the stripe model.
