Abstract

The powder X-ray diffraction data revealed that the structure of HoRhSn is isotypic with the hexagonal ZrNiAl type (space group P6‾2m). Bulk magnetic AC and DC measurements have shown that this compound is ferromagnetic with a Curie temperature of TC = 6.3(2) K. The thermal variation of the hyperfine parameters has been studied in detail by 119Sn Mössbauer spectroscopy. Especially, large distribution of magnetic hyperfine fields observed at the tin sites points to a rather complicated magnetic structure of probably non-collinear character but with the magnetic holmium moments arranged in directions close to the c-axis.
