Vortex pinning in layered organic superconductors: κ -(BEDT-TTF)2Cu[N(CN)2]Br.

Focuses on a magnetization study which examined field and temperature dependence of vortex pinning of organic single crystal superconductors with the field H parallel to the axis perpendicular to the conducting plane. Illustration of an overlay of the magnetization as a function of field at different temperatures; Description of the normalized relaxation rate as a function of field; Graph of irreversibility field as a function of temperature.
