Abstract
Synchrotron radiation x-ray diffraction experiments on the pressure-induced ferromagnetic superconductor UGe2 has been performed using a diamond anvil cell (DAC) diffractometer to study the correlation between the crystal structure and ferromagnetism. The oscillation photos covering the three-dimensional reciprocal spaces were taken both below and above a critical temperature Tx at pressures up to 1.1 GPa. Coupled charge density wave (CDW) and spin density wave (SDW) fluctuations were predicted as an origin of unusual properties of UGe2 by Watanabe and Miyake, but no additional superlattice Bragg peaks corresponding to the CDW reflections could be observed, resulting in an upper limit of its intensity of ∼ 1 x 10∼4 to the fundamental Bragg peak intensity.
