Neutron scattering study of magnetic Fe1+dTe thin films grown under tensile stress

Polarized neutron scattering reveals the presence of magnetic order in Fe1+dTe/MgO (0.04≤d≤0.1) grown under tensile stress. Neutron diffraction data shows the magnetic ordering with propagation vector (−0.5 0 −0.5) and the transition temperature is found TN≈67K from the temperature dependent measurement. In addition possible understanding of the strain effect on the lattice parameters of FeTe is discussed based on the present neutron data.
