  We construct new backgrounds of d-dimensional gravity with a negative
cosmological constant coupled to a m-form field strength. We find a class of
magnetically charged anti-de Sitter black holes with m-dimensional Einstein
horizon of positive, zero or negative curvature. We also construct a new
magnetic co-dimension four brane for the case of m=3. This brane obeys a charge
quantization condition of the form q \sim L^2 where q is the magnetic 3-form
charge and L is the AdS radius. In addition, we work out some time-dependent
solutions.
