The thermomagnetic stability of the Bean critical state in an anisotropic type-II superconducting slab is studied theoretically. It is predicted that in a strongly anisotropic superconducting slab the non-uniform, fingering-type instability appears as readily as in superconducting films. In particular, the fingering instability emerges for extremely low ramping rates of the external magnetic field.
