Abstract

A cluster‐glass (CG) Fe0.25Mg0.75TiO3 is investigated by muon spin relaxation measurements. It is found that the local magnetic fields at the muon stopping site are established at temperatures five times as high as the freezing temperature Tf. It is also found that the electron spins fluctuate even below Tf. The critical region around Tf in Fe0.25Mg0.75TiO3 is extremely wide in contrast to that of ordinary spin‐glass (SG) systems. It is clearly demonstrated that the microscopic and dynamical properties of CG are remarkably different from those of SG.
