Coexistence of ferro- and antiferromagnetic order in invar iron-nickel alloys
A neutron-diffraction method was used to investigate the magnetic structure of the disordered alloy Fe0.eaNio.37. It is shown for the first time that an antiferromagnetic order of the (4 h 0) type is produced at liquid-helium temperature on top of the usual ferromagnetic order. The Neel point T>j determined by measuring the temperature dependence of the peak intensity of the antiferromagnetic reflection was found to equal 15°K. The measurements results are interpreted within the framework of the noncollinear magnetic structure .
