Abstract

RMn₂ O₅ (R = Y and rare earth) shows successive magnetic and ferroelectric phase transitions at about 45, 40, 39, 20 and 10 K. We have reinvestigated the magnetic structure of YMn₂ O₅ at the commensurate phase (T = 25 K) using a single crystal four-circle diffractometer in order to discuss the mechanism of magnetoelectric interaction and the origin of ferroelectricity. We also observed the lattice modulation vectors (q_L) to compare the magnetic propagation vectors (q_M) by synchrotron X-ray diffraction. Improved magnetic structure data are compared with the theory recently proposed.
