Description
The magnetic structure of the compound HoFe2Ge2 (I4/mmm S.G) has been studied by neutron diffraction, magnetic and specific-heat measurements. The paramagnetic neutron data confirmed the ThCr2Si2 type of structure reported earlier for this compound. The analysis of the data collected in the magnetically ordered regime (TN=17 K) showed a uniaxial arrangement of the Ho moments along c associated with the wave vector q=(1/2,1/2,0). The moments of the atoms related by the non-primitive translation (1/2,1/2,1/2) are antiparallel. The refined moment value at 1.5 K is μHo=6.6(1) μB. In addition to the ordered phase the neutron data comprise diffuse magnetic peaks in the low-angle region demonstrating the coexistence of short-range order effects below 6 K. (orig.)
