| description | In type II superconductors the magnetic response 

can be irreversible due to two different reasons: vortex pinning and barriers for flux 

penetration. Even without bulk pinning and in absence of a microscopic Bean-Livingston 

surface barrier for vortex penetration, superconductors of nonellipsoidal shape can exhibit 

a large geometric barrier for flux penetration. This edge barrier and the resulting 

irreversible magnetization loops and flux-density profiles are computed from continuum 

electrodynamics for superconductor strips and disks with constant thickness, both without 

and with bulk pinning. Expressions are given for the field of first flux entry Hen and for 

the reversibility field Hrev above which the pin-free magnetization becomes reversible. 

Both fields are proportional to the lower critical field Hc1 but else depend only on the 

specimen shape. These results for rectangular cross section are compared with the well 

known reversible magnetic behavior of ideal ellipsoids.
