  The ferromagnetic phase transition in LaMnO3.14 is investigated by measuring
the dc magnetization as a function of magnetic field and temperature. Modified
Arrott plot and Kouvel Fisher analysis yield estimates for the critical
exponents beta, and gama, with values between that predicted for the Heisenberg
model and mean field theory. At low fields we found an anomalous small value of
beta, indicating that the critical behavior is influenced by the range of
magnetic fields used.
