The local magnetic field in the bulk of superconducting single crystal ␤ tin was measured near and across the transition between the normal ͑N͒ and intermediate ͑I͒ state at Tϭ0.08 K. With varying applied field H a , the data indicate a reversible phase transition within the I state at H t Ϸ295 Oe, interpreted as a transition from the laminar to a tubular structure. Near the I→N transition, occurring at H cI ϭ0.98H c0 ϭ300 Oe, the field B in the N domains is strongly inhomogeneous with B ϽH c0
