Notes:
Microwave-absorption measurements have been performed in Gd2CuO4 particles of controlled size. We have measured the microwave absorption associated with a magnetic resonance of the weak-ferromagnetic component of the magnetization. The onset temperature of this signal, related to the appearance of weak ferromagnetism, is depressed when the particle size is decreased. A simultaneous depression of the Néel temperature is suggested as the origin of the observed dependence, due to the limitation on the two-dimensional correlation length imposed by the particle size. © 1996 American Institute of Physics.
