Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices
Organic photovoltaics (OPVs) offer a promising solution for indoor energy harvesting. However, fundamental investigations to understand and optimize industrial processes such as roll-to-roll lamination for upscaling remain limited. This study investigates a critical failure mode in the upscaling of OPVs.
One major challenge ...
Absence of Altermagnetic Magnon Band Splitting in MnF2
Altermagnets are collinear compensated magnets in which the magnetic sublattices are related by rotation rather than translation or inversion. One of the quintessential properties of altermagnets is the presence of split chiral magnon modes. Recently, such modes have been predicted in MnF2.
Here, we report inelastic neutron scattering results ...

Pressure effect on the spin density wave transition in La2PrNi2O6.96
High-pressure studies reveal a stark contrast between the superconducting properties of double-layer Ruddlesden-Popper (RP) nickelates La2PrNi2O7 and La3Ni2O7. While La2PrNi2O7 exhibits bulk superconductivity, La3Ni2O7 displays filamentary behavior, suggesting that superconductivity is confined to phase interfaces rather than the bulk. Since magnetism emerges ...
E-MRS 2025 Spring Meeting Young Researcher Award for Mohammadhossein Montazerian
During its recent spring meeting the European Materials Research Society has awarded the E-MRS Young Researcher Award to Mohammadhossein Montazerian from the LMX laboratory in recognition of his "Outstanding contribution to the Symposium L: Solid state batteries - materials, processing and advanced characterization".
Pressure tuning of competing interactions on a honeycomb lattice
Exchange interactions are mediated via orbital overlaps across chemical bonds. Thus, modifying the bond angles by physical pressure or strain can tune the relative strength of competing interactions. Here we present a remarkable case of such tuning between the Heisenberg (J) and Kitaev (K) exchange, which respectively establish magnetically ordered and spin liquid phases on a honeycomb lattice. We observe ...
