A low concentration paramagnetic center stemmimg from the initial amoprhous boron powder along with traces of (formula presented) impurities are identified in the ESR spectra. Intense microwave absorption, that distorts CESR below (formula presented) is observed in fine powders implying enhanced microwave dissipation due to the viscous flux motion. © 2002 The American Physical Society.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 1</style></notes></record></records></xml>
