This article reports finding of a highly oxidised mineral in diamond inclusion derived from mantle transition zone or lower mantle, very reduced areas on our planet. Such oxidised material is likely linked to subduction of carbonates into this region

Magnetic Ordering of Magnetite Inclusions in Olivine at Mantle Depths in Subduction Zones

Autor: Marcello Campione, Mara Murri, Valerio Cerantola, Dimitrios Bessas, Anja Rosenthal, Aleksandr Chumakov, Marco Scambelluri, Nadia Malaspina

Publikováno v: ACS Earth and Space Chemistry. 6:2755-2759

Magnetite microinclusions in metamorphic harzburgites, derived from the deserpentinization of the subducted hydrated oceanic lithospheric mantle, were examined by synchrotron Mössbauer spectroscopy to investigate the chemical and magnetic environmen

Ultra-high precision x-ray polarimetry with artificial diamond channel cuts at the beam divergence limit

Autor: Hendrik Bernhardt, Annika T. Schmitt, Benjamin Grabiger, Berit Marx-Glowna, Robert Loetzsch, Hans-Christian Wille, Dimitrios Bessas, Aleksandr I. Chumakov, Rudolf Rüffer, Ralf Röhlsberger, Thomas Stöhlker, Ingo Uschmann, Gerhard G. Paulus, Kai S. Schulze

Publikováno v: Physical Review Research, Vol 2, Iss 2, p 023365 (2020)

We report on the use of synthetic single-crystal diamonds for high definition x-ray polarimetry. The diamonds are precision mounted to form artificial channel-cut crystals (ACCs). Each ACC supports four consecutive reflections with a scattering angle

Сanted Magnetic Interlayer Ordering in a [Fe(3.0 nm)/Cr(1.2 nm)]10 Structure Revealed by Synchrotron Mössbauer Reflectometry with Polarization Analysis

Autor: R. A. Baulin, Dimitrios Bessas, A. I. Chumakov, D. N. Karimov, Boris S. Roshchin, Marina A. Andreeva, V. E. Asadchikov

Publikováno v: JETP Letters. 113:162-168

Mossbauer reflectivity spectra measured for the [Fe(3.0 nm)/Cr(1.2 nm)]10 structure in the half-order Bragg peak, which corresponds to the doubling of the period, have revealed the formation of a canted antiferromagnetic structure under the action of

Compressibilities along the magnetite-magnesioferrite solid solution

Autor: Caterina Melai, Tiziana Boffa-Ballaran, Laura Uenver-Thiele, Alexander Kurnosov, Aleksandr I. Chumakov, Dimitrios Bessas, Daniel J. Frost

In order to calculate the thermodynamic properties for recently discovered high-pressure mixed valence iron-oxides in the system Fe-Mg-O, information on the equation of state of precursor inverse spinel phases along the magnetite-magnesioferrite join

Ultra-low Hysteresis in Giant Magnetocaloric Mn1-xVxFe0.95(P,Si,B) Compounds

Autor: Jiawei Lai, Xinmin You, Jiayan Law, Victorino Franco, Bowei Huang, Dimitrios Bessas, Michael Maschek, Dechang Zeng, Niels van Dijk, Ekkes Brück

Publikováno v: Journal of Alloys and Compounds, 930(167336)

Large thermal hysteresis in the (Mn,Fe)2(P,Si) system hinders an efficient heat exchange and thus limits the magnetocaloric applications. Substitution of manganese by vanadium in the Mn1-x1Vx1Fe0.95P0.593Si0.33B0.077 and Mn1-x2Vx2Fe0.95P0.563Si0.36B0
