Abstract Magnetic torque of the single crystal of a layered superconductor κ-(BEDT-TTF)2Cu[N(CN)2]Br has been measured as a function of field direction with respect to the b-axis under several magnetic fields H up to 8 kOe in the temperature range from 1.5 to 20 K. Smaller value of the anisotropy parameter γ = 180 is obtained for Cu[N(CN)2]Br salt than our previous report γ = 350 for κ-(BEDT-TTF)2Cu(NCS)2. The irreversible region in H — T phase diagram for Cu[N(CN)2]Br salt with smaller γ is larger than that for Cu(NCS)2 salt. A sharp cusp due to the intrinsic pinning is found near H∥ac-plane as in the case of our previous report on other layered superconductors.
