Özet

We report the structure and magnetic properties of Pr1-xHoxMn2Ge2 (0.0 ≤ x ≤ 1.0) germanides by means of X-ray diffraction (XRD), differential scanning calorimetry (DSC) techniques and AC magnetic susceptibility measurements. All compounds crystallize in the ThCr2Si2-type structure with the space group I 4 / m m m. Substitution of Ho for Pr leads to a linear decrease in the lattice constants and the unit cell volume. The samples with x = 0 and x = 0.8 have spin reorientation temperature. The results are collected in a phase diagram. © 2006 Elsevier Ltd. All rights reserved.
