SPIN-DENSITY-WAVE ANTIFERROMAGNETISM IN THE CHROMIUM SYSTEM .2. CRITICAL-FLUCTUATIONS AND HIGH-TEMPERATURE FLUCTUATIONS, SPIN-GLASS BEHAVIOR IN CRMN

The effect of V-doping on the critical fluctuations in Cr observed by inelastic neutron scattering is reviewed. The recent observation of an omalously high thermal expansion in Cr at temperatures approaching the melting point is discussed in relation to work that seemed to show th at there is a magnetovolume associated with spin fluctuations seen up to about twice the Neel temperature. Cr alloys containing Mn exhibit m any characteristic spin-glass properties; work on binary CrMn alloys i s reviewed.
