AB  - Due to its cooperative nature, magnetic ordering involves a complex interplay 
      between spin, charge, and lattice degrees of freedom, which can lead to strong 
      competition between magnetic states. Binary Fe(3)Ga(4) is one such material that 
      exhibits competing orders having a ferromagnetic (FM) ground state, an 
      antiferromagnetic (AFM) behavior at intermediate temperatures, and a conspicuous 
      re-entrance of the FM state at high temperature. Through a combination of neutron 
      diffraction experiments and simulations, we have discovered that the AFM state is 
      an incommensurate spin-density wave (ISDW) ordering generated by nesting in the 
      spin polarized Fermi surface. These two magnetic states, FM and ISDW, are seldom 
      observed in the same material without application of a polarizing magnetic field. 
      To date, this unusual mechanism has never been observed and its elemental origins 
      could have far reaching implications in many other magnetic systems that contain 
      strong competition between these types of magnetic order. Furthermore, the 
      competition between magnetic states results in a susceptibility to external 
      perturbations allowing the magnetic transitions in Fe(3)Ga(4) to be controlled 
      via temperature, magnetic field, disorder, and pressure. Thus, Fe(3)Ga(4) has 
      potential for application in novel magnetic memory devices, such as the magnetic 
      components of tunneling magnetoresistance spintronics devices.
