Abstract

Magnetic susceptibility and nuclear magnetic resonance of Cu and Cl nuclei have been studied in monocrystals of [C₆H₅(CH₂)_nNH₃]₂CuCl₄ with n=1,2,3 below 4.2 K. These compounds are two‐dimensional ferromagnets with a dominant XY‐type anisotropy. For the compound with n=1, the Ising anisotropy is extremely small. The NMR measurements of the temperature and field dependence of the magnetization are consistent with a two‐dimensional spin‐wave model and allowed us to determine the value of the intralayer exchange integral.
