57Fe Mössbauer effect studies of La1.65Eu0.20Sr0.15CuO4 doped
with 0.5 at% 57Fe performed in the temperature region 300 K > T > 4.2 K give
an onset temperature for magnetic ordering of 
K. This temperature
practically is the same as that found in Nd doped La
SrxCuO4. It
indicates that the magnetic ordering temperature in the LTT phase of rare earth (RE)
doped LaSrxCuO4 is independent of the RE moment. The direction of the
57Fe magnetic moment in the magnetically ordered state is within the CuO2 plane,
while it has been found to be parallel to the c-axis in Nd doped
LaSrxCuO4.
