  We present measurements of the magnetic susceptibility chi(T) on Cu2Te2O5Br2
under externally applied pressure. From our data we extract the pressure
response of the antiferromagnetic phase transition at T0 = 11.6 K and of the
overall magnetic coupling strength. Our experiments indicate that with pressure
the overall magnetic coupling strength increases by about 25% with applied
pressure of only 8 kbar. In contrast, the phase transition temperature T0 is
significantly suppressed and not observable anymore at a pressure of already
8.2 kbar.
