Abstract

Neutron diffraction studies of the spin-density-wave (SDW) behaviour in antiferromagnetic (Cr_98.4Al_1.6)_100-yMo_y with y = 0, 3.7 and 4.2, as well as (Cr_100-xAl_x)₉₅Mo₅ with x = 0 and 4.6 alloy systems are reported. The results confirm an incommensurate (I) SDW to paramagnetic (P) phase transition at the quantum critical point of the (Cr_98.4Al_1.6)_100-yMo_y series. In addition two further quantum critical magnetic phase transitions are proposed for the (Cr_100-xAl_x)₉₅Mo₅ series, one from ISDW to P and the other from P to commensurate (C) SDW.
