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 T-N approximate to 67 K 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. (C) 2015 Elsevier B.V. All rights reserved.
