摘要:

Studies of EPR intensity and linewidth in four free radicals at temperatures between 300° and 1.5°K have shown the presence of antiferromagnetic exchange coupling. In two cases a low‐temperature paramagnetism occurs following a Curie‐Weiss law with positive Weiss constant. A model involving isolated spins in a magnetically dilute system is proposed to explain these results.
