Abstract

The weak dissipation of spin waves in magnetic materials make antiferromagnets realistic condensed matter systems for the experimental observation of intrinsic localized modes of nanoscale size. By employing a chirped high power microwave pulse, a few microseconds long, the lowest frequency antiferromagnetic uniform mode of the quasi-one-dimensional biaxial antiferromagnet (C2 H5 NH3 )2 CuCl4. has been efficiently driven into an unstable dynamical region. Intrinsic localized spin waves form below the gap. Our experimental findings demonstrate that a simple optimal control scheme can be used to investigate this kind of nonlinear excitation.
