Abstract
The results of experimental study of static magnetic properties, AC nonline ar magnetic susceptibility, and microwave spin dynamics of the quasi-2D Hei senberg antiferromagnets R2CuO4 (R = Eu, Pr and Gd) are presented. The anal ysis of results shows that in these crystals in wide temperature range, bel ow as well as above the Neel temperature, there is a state of the Random Fi eld-type - the quasi-2D antiferromagnetic order is present only in domains of limited scale and 2D Heisenberg antiferromagnetic spin fluctuations with large correlation radius exist.
