  • Hard ferrimagnetism in the layered magnet $\mathrm{L}{\mathrm{i}}_{4}\mathrm{M}{\mathrm{n}}_{2}\mathrm{T}{\mathrm{e}}_{2}{\mathrm{O}}_{11}$

    Author(s): Xianghan Xu and R. J. Cava We report on the characterization of $\mathrm{L}{\mathrm{i}}_{4}\mathrm{M}{\mathrm{n}}_{2}\mathrm{T}{\mathrm{e}}_{2}{\mathrm{O}}_{11}$, a previously unstudied layered oxide that exhibits ferrimagnetic ordering below 30 K and an exceptionally large coercive field exceeding 9 T at 2 K. The crystal str… [Phys. Rev. Materials 9, 114417] Published Thu Nov 20, 2025

  • Realization of a triangular spin necklace in a verdazyl-based Ni complex

    Author(s): Itsuki Shimamura, Risa Yagura, Takanori Kida, Masayuki Hagiwara, Koji Araki, Yoshiki Iwasaki, Yuko Hosokoshi, Kenta Kimura, and Hironori Yamaguchi We successfully synthesized a verdazyl-based complex, ${(m\text{−}\mathrm{Py}\text{−}\mathrm{V})}_{3}[\mathrm{Ni}{({\mathrm{NO}}_{3})}_{2}]$, in which ${\mathrm{Ni}}^{2+}$ ions and verdazyl radicals form a one-dimensional, triangular spin necklace consisting of spin-1/2 and spin-1 units....

  • Reaction pathway variability in electrochemical conversion reactions for ion batteries

    Author(s): Jordan Sweeney, Kieran McDonnell, and Eve M. Mozur Conversion cathodes are attractive for next-generation ion batteries, owing to their large specific capacities. However, candidate materials suffer from limited electrochemical reversibility. The authors propose that cathode reversibility is directly related to the structural transformations of active materials during charge and discharge. Through a selection of case studies, we demonstrate...

  • Doping-induced spin reorientation in kagome magnet ${\mathrm{TmMn}}_{6}{\mathrm{Sn}}_{6}$

    Author(s): Mohamed El Gazzah, Po-Hao Chang, Y. Lee, Hari Bhandari, Resham Regmi, Xiuquan Zhou, Liqin Ke, Igor I. Mazin, and Nirmal J. Ghimire The kagome-lattice compounds $R{\mathrm{Mn}}_{6}{\mathrm{Sn}}_{6}$ ($R$ is a rare-earth element), where the Mn atoms form a kagome net in the basal plane, are currently attracting a great deal of attention as they have been shown to host complex magnetic textures and electronic topological states st… ...

  • Coexistence of ferroelectricity and ferromagnetism in vanadium-doped ${\mathrm{HfO}}_{2}$

    Author(s): Vincenzo Fiorentini, Paola Alippi, and Gianaurelio Cuniberti Ab initio density-functional calculations show that orthorhombic $Pca{2}_{1}$ hafnia ${\mathrm{HfO}}_{2}$ mixed with vanadium at low concentration is a ferroelectric and ferromagnetic insulator. The multiorbital degeneracy of singly-occupied V states in the nominally $4+$ ionic state is broken by ma… [Phys. Rev. Materials 9, 114415] Published Wed Nov 19, 2025

  • Inverse garnet/Pt heterostructures by lateral crystallization

    Author(s): Christian Holzmann, Stephan Glamsch, David Stein, Maximilian Mihm, Aladin Ullrich, Richard Schlitz, Michaela Lammel, Johannes Boneberg, and Manfred Albrecht Rare-earth iron garnet thin films are widely used in magnonics and spintronics because of their insulating nature and unique magnetic properties, such as low Gilbert damping and a tunable magnetic anisotropy. However, these properties are mostly restricted to single-crystalline...

  • Tuning superconductivity in sputtered ${\mathrm{W}}_{0.75}{\mathrm{Re}}_{0.25}$ thin films

    Author(s): F. Colangelo, F. Avitabile, Z. Makhdoumi Kakhaki, Abhishek Kumar, A. Di Bernardo, C. Bernini, A. Martinelli, A. Nigro, C. Cirillo, and C. Attanasio ${\mathrm{W}}_{\text{0.75}}{\mathrm{Re}}_{\text{0.25}}$, in its bulk form, is an interesting superconducting material due to its multiple crystalline phases, each exhibiting distinct superconducting characteristics. However, little is known about how these phases manifest in thin-film form...
