Synthesis, Structure and Magnetic Properties of Multilayer Nanoheterostructures Fe|MgO|Cr|MgO|Fe
Layered nanoheterostructure Fe|MgO|Cr|MgO|Fe is an artificial ferromagnetic material in which exchange interaction of magnetic moments in the iron layers through intermediate dielectric and metal layers can lead to magnetic configurations which do not appear in well-studied systems Fe|MgO|Fe and Fe|Cr|Fe. In this work correlations of the structural and magnetic properties of layered nanoheterostructures Fe(10 nm)|MgO(1.5 nm)|Cr(t nm)|MgO(1.5 nm)|Fe(7 nm) (with the thickness t being 0.9 and 1.8 nm) were studied.

Neutron crystallographic analysis of the nucleotide- binding domain of Hsp72 in complex with ADP
IUCrJ 9(4), 1-13 () [10.1107/S2052252522006297]
The 70kDa heat-shock proteins (Hsp70s) are ATP-dependent molecular chaperones that contain an N-terminal nucleotide-binding domain (NBD) and a C-terminal substrate-binding domain. Hsp70s bind to misfolded/unfolded proteins and thereby prevent their aggregation. [...]

Frustration model and spin excitations in the helimagnet FeP
The metallic compound FeP belongs to the class of materials that feature a complex noncollinear spin order driven by magnetic frustration. While its double-helix magnetic structure with a period λs≈5c, where c is the lattice constant, was previously well determined, the relevant spin-spin interactions that lead to that ground state remain unknown.

Magnetic phase diagram of HoFeO$_3$ by neutron diffraction
Neutron diffraction studies of HoFeO 3 single crystals were performed under external magnetic fields. The interplay between the external magnetic fields, Dzyaloshinsky-Moria antisymmetric exchange and isotropic exchange interactions between Fe and Ho sublattices and within the Fe sublattice provides a rich phase diagram.

Crystal symmetry of stripe-ordered La$_{1.88}$Sr$_{0.12}$O$_4$
We present a combined x-ray and neutron diffraction study of the stripe ordered superconductor La$_{1.88}$Sr$_{0.12}$O$_4$. The average crystal structure is consistent with the orthorhombic Bmab space group as commonly reported in the literature. [...]

Small-angle neutron scattering applied to low-dose neutron-irradiated Fe–Cr alloys and ferritic martensitic steel Eurofer97
Ferritic/martensitic (F/M) Fe–Cr-based steels are candidates for applications in nuclear fission and fusion. Previous experimental results for neutron-irradiated binary Fe–Cr alloys and high-dose neutron-irradiated F/M steels contributed greatly to the understanding of the irradiation behaviour of these groups of materials.

Effect of Thermal Stimulus on Kinetic Rehydration of Thermoresponsive Poly(diethylene glycol monomethyl ether methacrylate)- block -poly(poly(ethylene glycol) methyl ether methacrylate) Thin Films Probed by In Situ Neutron Reflectivity
Langmuir 38(26), 8094 - 8103 () [10.1021/acs.langmuir.2c00940]
The kinetic rehydration of thin di-block copolymer poly(diethylene glycol monomethyl ether methacrylate)-block-poly(poly(ethylene glycol) methyl ether methacrylate) (PO2-b-PO300) films containing two thermoresponsive components is probed by in situ neutron reflectivity (NR) with different thermal stimuli in the D2O vapor atmosphere. The transition temperatures (TTs) of PO2 and PO300 blocks are 25 and 60 °C, respectively. [...]
