We report muSR studies of the recently synthesized I2-doped phenylened
iamine polymer. Longitudinal-field spectra exhibit typical behavior of
a spin-glass with a freezing temperature T approximately 100 K and a
spontaneous static local field approximately 500 G at low temperatures
. Preliminary magnetization measurements hint of antiferromagnetic spi
n coupling and hysteretic behavior around T(g). These features suggest
possible spin-glass and/or antiferromagnetic spin freezing with a hig
h transition temperature due to the doped radical spins in this organi
c polymer.
