N2 - The phase diagram under magnetic fields in the organic Mott system κ-(BEDT-TTF)2Cu[N(CN)2]Br in which the bandwidth was tuned by the substitution of deuterated molecules was studied by means of the resistivity measurements. The lower critical point of the first-order Mott transition, which ended on the upper critical field H c2-temperature plane of the superconductivity, was found in addition to the previously observed upper critical end point. The lower critical end point moved to a lower temperature together with the suppression of T c in magnetic fields and then it reached T 0 when H > H C2 in the end.
