| Description | Journal: Journal of Physics: Condensed Matter The magnetic phase diagram of the intermetallic compounds has been studied under pressure using neutron diffraction. At ambient pressure all compounds undergo a first-order magnetic transition as the Mn magnetic moment becomes local, giving rise to a transformed phase, with higher volume. Part of the sample can remain non-transformed and the two phases coexist below the transition temperature. As pressure is applied the relative volume percentages of the transformed phase and non-transformed phases change as the transformed phase becomes unstable under pressure. At high enough pressures only the non-transformed phase is present. Within the non-transformed phase, for x > 0.2 there is a transition to a magnetic structure which is reminiscent of the -like structure while for the structure remains paramagnetic. In the transformed phase the -like magnetic structure develops at high Tb concentrations while at low Tb concentrations two different antiferromagnetic structures are visible, a -like structure and a new antiferromagnetic structure unknown up to now. Across the intermediate-concentration range a magnetic ground state with short-range correlations is present. |
