✦ Synopsis

Antiferromagnetic resonance is studied in single crystals of CuCI2.2H20 at a frequency of 32000 MHz and temperatures from 1.35°K to 4.3°K. The constant field was applied along different directions in the aband the at-plane. One of the observed resonances occurred on the threshold hyperbola and had a width of only 15 ~ at the lowest temperature. Other resonances permitted the determination of the parameters: He: H a and a, which characterize respectively: the anisotropy of the exchange field in two directions and the anisotropy of the susceptibility. On the whole the agreement with the earlier data at 9400 MHz and with the theoretical expectations of U b b i n k and Y o s i d a is excellent. Below about 2.5°K a so far unexplained structure of certain resonances was observed. Incidentally a few data are given on the g-values and widths of the paramagnetic resonance above the N6el temperature.

## Synopsis The theories of U b b i n k and Y o s i d a have been compared with the experiments on CuC12.2H20 at 32 000 MHz. Within the accuracy of the experiments a complete agreement has been found with these theories; the experiments gave the values: H c = 6500 O and H a -~-9150 O. The temper
