  The compound alpha-Fe1.4Ga0.6O3 has been prepared by mechanical alloying of
alpha-Fe2O3 and Ga2O3 and subsequent heating of the mechanical alloyed samples
in vacuum condition. Magnetic ordering of alpha-Fe2O3 has been modified by
substitution of non-magnetic Ga atoms. The ferromagnetism in alpha-Fe1.4Ga0.6O3
is more soft and enhanced in comparison to alpha-Fe2O3. M\"ossbauer
spectroscopy also confirmed enhanced ferromagnetic order in alpha-Fe1.4Ga0.6O3.
The room temperature soft ferromagnetism by Ga substitution is interesting for
designing alpha-Fe2O3 based unconventional ferromagnet, which is a great
challenge to the materials scientists. The alpha-Fe1.4Ga0.6O3 samples also
exhibited features of exchange bias, low temperature surface paramagnetism, and
suppression of Morin transition. These features have been affected up to
certain extent by the nano-sized grains of the samples.
