Nonlinear, field-modulated, direct microwave absorption (FMMA) was observed in copper-free Ba~ ,K~BiO3 powder sampies. The high-field, low-temperature results were compared to previous measurements ofYBa CuO and BiSrCaCuO. The microwave determined critical field #oH\* = 0.7 p\_T and depinning curren

We present new results on the optical absorption of the family of compounds KxBa~ \_xBiO3 (KBB) and CsxKo.4\_xBao.6BiO3 (CKBB) (0 < x < 0.4 ) using powder methods. All cubic compounds of the KBB system (x >/0.3, Tc ~ 30 K) possess a broad nearinfrared (NIR) absorption band, which appears to evolve o
