We performed a magnetic characterization of Ba(Fe0.9Co0.1)2As2polycrystal. We show the hysteretic behavior as a function of the magnetic field, the AC susceptibility and the magnetization as a function of temperature. When compared with single crystals, our Jcvalues are lower whereas the Hirr ones are higher, probably due to intergrain weak links and different critical temperatures. © 2009 Elsevier B.V.
