Abstract:

The magnetic susceptibility of cupric nitrate trihydrate CuNO32 2.5H2O has been meas ured on the powder and on single crystals in the 14-20 and 0.4-4.2 K ranges of temperature. The susceptibility of the powder has a rounded maxi mum at 3.2 K, where it is equal to 0.065 CGSmole, and drops very rapidly towards zero below this temperature. This behavior differs from that of a typical antiferromagnet. The experimental data have been compared with existing theoreti cal calculations for antiferromagnetic linear chains or binary clusters. In the single crystal, the susceptibility measured in a direc tion parallel to the monoclinic axis is always larger by 20 than the susceptibility in the perpendicular directions. This is probably due to a uniaxial anisotropy of the g factor.
