| Abstract: | The magnetic susceptibility of Cu3(C6H5N2O)3(OH)SO4 · 10.5 H2O crystals was measured in the temperature interval 4.2–11 K and magnetic field range 0–50 kOe. The theoretical analysis of the effects of antisymmetric exchange was performed. An adequate interpretation of the experimental results may be done in terms of an antisymmetric exchange which is about 12 cm?1 in the crystals discussed. The rhombic distortions of the trigonal cluster were shown to reduce the antisymmetric exchange. |
