Measurements of paramagnetic diffuse scattering in a single crystal of MnF2
were done in complete (h k 0) and (h 0 1) planes at the Flat-cone diffract
ometer E2. of the Berlin reactor. The data have been evaluated with an exte
nded molecular field theory up to a temperature of 170 K (TN = 67.4 K). Goo
d agreement with the experiment could be achieved by introducing a renormal
ized temperature as parameter. This parameter describes the transition betw
een the critical and the molecular field region. (C) 2000 Elsevier science
