| Abstract: | We have used neutron diffraction and 57Fe M€ossbauer spectroscopy, complemented by magnetisation and specific heat measurements, to examine the magnetic ordering of Ho2Fe2Si2C. We have established that Ho2Fe2Si2C orders antiferromagnetically below TN¼ 16(1) K with a magnetic structure involving ordering of the Ho sublattice along the b-axis with a propagation vector k ¼ ½0 0 12. 57Fe M€ossbauer spectra collected below TN show no evidence of a magnetic splitting, demonstrating the absence of long range magnetic ordering of the Fe sublattice. A small line broadening is observed in the 57Fe spectra below TN, which is due to a transferred hyperfine field—estimated to be around 0.3 T at 10 K—from the Ho sublattice.
