Abstract:

The magnetic ordering of Ce2Fe17 and Ce2Fe16Mn at ambient and under high pressures up to 5 kbar was studied by neutron diffraction in the temperature range 2-300 K. The existence of collinear ferromagnetic (below 94 K) and incommensurate helical antiferromagnetic structures with a propagation vector τ1 = (0, 0, τ1z) was found at ambient pressure in Ce2Fe17. A helical structure with τ2 = (0, 0, τ2z) exists below 200 K down to low temperatures in Ce2Fe16Mn. Application of pressure results in the suppression of the ferromagnetic phase in Ce2Fe17 by P > 3 kbar. A new pressure-induced incommensurate antiferromagnetic phase appears at T < 80 K. This phase is characterized by an additional satellite with τ3 = 0.078 Å-1 at 5 kbar. The helical structure of Ce2Fe16Mn significantly changes under pressure. Below 70-80 K at P > 3 kbar it transforms to a non-collinear phase, which can be described using a distorted elliptical spiral model.
