The ESR intensity and the Dzyaloshinsky-Moriya interaction of the   nanoscale molecular magnet V15
  The intensity of electron spin resonance (ESR) of the nanoscale molecular magnet V15 is studied. We calculate the temperature dependence of the intensity at temperatures from high to low. In particular, we find that the low-temperature ESR intensity is significantly affected by the Dzyaloshinsky-Moriya interaction.
