Abstract
The far-infrared optical transmission has been studied for two lanthanide-based single-chain magnets and in the frequency range between 3 and 80 . The spectra were acquired at temperatures between 2 and 80 K and magnetic fields up to 6 T. Based on their magnetic field dependence in two of the observed absorption lines are identified as transitions inside the crystal field split ground multiplet , coupled to the neighboring spins. In one transition was observed inside the crystal-field-split ground multiplet . The results allow a spectroscopic investigation of the role of single-ion anisotropy and exchange in Glauber dynamics.
