Abstract

Small-angle neutron-scattering and some magnetic measurements of Cr0.81Mn0.19Ge gave evidence of a double transition, from a paramagnetic to a helical magnetic state, and to a mixed state of helical and spin-glass-like ordering with decreasing temperature. The helical spin modulation, having a long period (from 360 at 5.3 K to 420 at 12.5 K), indicates the nature of an itinerant-electron-type magnet, and the reentrant transition is interpreted on the basis of the interacting spin fluctuation.
