  We present the follow-up of two galaxy clusters from the Bright and Southern
SHARC surveys observed with the XMM-Newton satellite. We studied the galaxy
cluster RX J1120.1+4318 which seems to be a relaxed cluster at high redshift
according to its surface brightness profile and to its temperature profile
which is flat up to 950 kpc. Its mean temperature is measured at 5.3 keV. The
other galaxy cluster RX J0256.5+0006 shows two components. We discuss possible
scenario.
