We report a detailed measurement of the magnetization for a high-quality Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub 8] single crystal as a function of magnetic field ([bold H]) and the angle between [bold H] and the [ital c]-axis, near the transition temperature [ital T][sub [ital c]]. The fluctuation magnetization for [bold H] parallel to the [ital c]-axis was found to be in excellent agreement with the recently developed vortex-fluctuation theory by Bulaevskii [ital et] [ital al]. and the order-parameter fluctuation theory by Te[hacek s]anovic [ital et] [ital al]. However, our fluctuation magnetization data for the fields, applied at a large angle with respect to the [ital c]-axis, were found inconsistent with the expectations from the above theories.
