Abstract We report an upward curvature in the temperature dependence of the upper critical field {ital H}{sub {ital c}2}({ital T}) in K{sub {ital x}}Ba{sub 1{minus}{ital x}}BiO{sub 3} single crystals using ac-susceptibility measurements and magnetic fields up to 25 T. A possible role of Landau quantization in such uncommon behavior is discussed. {copyright} {ital 1996 The American Physical Society.}
