Magnetic measurements are presented for polycrystalline samples of californium trichloride in both a hexagonal (UCl/sub 3/ type; Cf(III) C.N. = 9) and orthorhombic (PuBr/sub 3/ type; Cf(III) C.N. = 8) crystal form. In the Curie-Weiss temperature region the Weiss constant, theta/sub p/, is significantly larger for the orthorhombic form. The susceptibility of the orthorhombic form deviates from Curie-Weiss behavior at a higher temperature than the hexagonal form indicating a larger crystal field splitting in the former. At temperatures below 15 K a field dependent transition is observed. In a field of 5 kG an antiferromagnetic maximum in the susceptibility is observed at 7 K and 13 K for the hexagonal and orthorhombic forms, respectively. For 30 kG both types exhibit monotonically increasing susceptibilities with lower temperature and the hexagonal form shows saturation behavior in the susceptibility versus temperature plots with a saturation moment of approx.7 ..mu../sub B//atom. 6 refs., 3 figs.
