| Research Abstract |
In a system without randomness or imperfections we have not expected to observe a time variation of magnetic property within an attainable time scale. Contrary to all expectations, we found a long-time variation of magnetic structure in a non-diluted uniform magnet CeIr3Si2 by means of time-resolved neutron scattering measurements. We examined other materials and found similar long-time variations of magnetic structure in several materials. In this study we have clarified that the peculiar long-time variation of magnetic structure in these materials is an intrinsic property caused by frustrated magnetic interactions.
