La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.

High‐purity X‐ray polarimetry at high energies for Mössbauer spectroscopy
This work extends high‐purity X‐ray polarimetry into the 15–30 keV range, enabling polarization‐filtered synchrotron Mössbauer spectroscopy of higher‐energy nuclear resonances. A proof‐of‐principle experiment at 22.494 keV demonstrates a polarization purity of (1.2 ± 0.5) × 10−8, establishing the feasibility of the approach.High‐purity X‐ray ...

Magnetic and Structural Characterization of Mechanically Alloyed Fe50co50 Samples
Samples of nominal composition Fe50Co50 were produced by mechanical alloying byusing a planetary ball mill and different milling times. The samples were studied via X-raydiffraction, Mössbauer spectroscopy, and X-ray photoelectron spectroscopy to ...

High‐resolution monochromator for the 8.41 keV 169Tm nuclear resonance
A high‐resolution monochromator for the 8.41 keV 169Tm nuclear resonance is presented enabling nuclear resonant scattering on Tm compounds at PETRA III beamline P01. Hyperfine parameters and phonon densities of states of metallic Tm and Tm2O3 are studied.Rare‐earth elements are key components in a wide range of functional materials, including solid ...

P‐T Uncertainty in Subsolidus Metamorphic Systems: Sources, Patterns and Controls
ABSTRACT Phase equilibrium modelling of metamorphic rocks is subject to multiple, superimposed sources of uncertainty that affect pressure–temperature (P$$ P $$‐T$$ T $$) estimates, making it difficult to independently distinguish and evaluate the contribution of each source.

Mössbauer and heat capacity studies of ErZnSn2
Heat capacity results obtained for the intermetallic compound ErZnSn2 were re-analysed to also consider, apart from the classical Debye model, the anharmonicity of the crystal lattice and the proper set of Einstein modes.
