Abstract
It is shown that the introduction of a very small amount of nonmagneti c impurities into the magnetic sites of a classical two-dimensional an tiferromagnet creates a new type of static (impurity-pinned) soliton t hat affects the Arrhenius, exp(-E/T), temperature-dependent electron p aramagnetic resonance linewidth by drastically changing the parameter E. Data just above the transition temperature for (C3H7NH3)(2)MxMn1-xC l4 confirm the existence of these impurity-pinned solitons.
