Experimental and computational study of the magnetic properties of ZrMn2-xCoxGe4O12
Polycrystalline samples in the solid solution ZrMn2-xCoxGe4O¬12 (x = 0.0, 0.5, 1.0, 1.5 and 2.0) have been prepared using the ceramic method and characterised by a combination of magnetometry, X-ray diffraction and neutron diffraction. They all adopt the space group P4/nbm with a ~ 9.60, c ~ 4.82 Å...

description | Polycrystalline samples in the solid solution ZrMn2-xCoxGe4O¬12 (x = 0.0, 0.5, 1.0, 1.5 and 2.0) have been prepared using the ceramic method and characterised by a combination of magnetometry, X-ray diffraction and neutron diffraction. They all adopt the space group P4/nbm with a ~ 9.60, c ~ 4.82 Å and show long-range magnetic order with transition temperatures, TC, in the range 2 ≤ TC/K ≤ 10. The underlying magnetic structure is the same in each case but the ordered spins lie along [001] when x = 0.0 and in the (001) plane for all other compositions. In all cases the magnetically-ordered phase is a weak ferromagnet although the magnitude of the spontaneous magnetisation and the strength of the coercive field are composition-dependent. The magnetic structure can be rationalized by considering the strengths of the interactions along the distinct M – O – Ge – O – M superexchange pathways in the crystal and the observed magnetic structure is entirely consistent with the predictions of ab initio calculations. |
