OSTI ID:5328689
The stage 2 CoCl/sub 2/-graphite intercalation compound exhibits two magnetic phase transitions at T/sub Cl/ (=8.0K) and T/sub Cu/ (=9.1K). We have performed neutron scattering experiments on this compound which revealed at T < T/sub Cl/ a spin structure in which the 2D ferromagnetic CoCl/sub 2/-sheets are stacked antiferromagnetically along the c-axis with weak 3D correlation. The intermediate phase between T/sub Cl/ and T/sub Cu/ is purely 2D in character with ferromagnetic in-plane order. 6 refs., 3 figs.
