a Crystal structure of FeZr2. b XRD pattern of the bulk sample FeZr2 measured inside the RD–RD (RD: radial direction) plane. c Rietveld refinements of SXRD patterns for FeZr2. d Linear thermal expansion measured by a thermo-dilatometer along the vertical direction on heating (93 to 423 K, 300 to 1078 K). e Temperature dependence of the lattice parameter c extracted from NPD, and the change of lattice constant c, △c, extracted by nPDF and SXRD.
