Quantum spin ladder with ferromagnetic rungs in Bi $_{2}$ CuO $_{3}$ (SO $_{4}$ )

Rodolfo A. Rangel Hernandez, Kirill Yu. Povarov, Sergei Zvyagin +3

We introduce Bi $_{2}$ CuO $_{3}$ (SO $_{4}$ ) as a rare example of a spin-ladder magnet with ferromagnetic interactions on the rungs. Its magnetic response is studied through measurements of…

Revisiting the symmetry and optical phonons of altermagnetic $I^\pm$ -MnTe

Ece Uykur, Marcos V. GonÃ§alves-Faria, Sahana RÃ¶Ãler +5

Using infrared (IR) and Raman spectroscopies combined with high-resolution x-ray diffraction, we address several controversial aspects of altermagnetic $I^\pm$ -MnTe. We show that mech…

Low-field magnetization processes of hexagonal easy-plane altermagnet $I^\pm$ -MnTe

Sahana RÃ¶Ãler, Victoria Ginga, Marcus Schmidt +5

Single crystals of $I^\pm$ -MnTe were synthesized by chemical vapor transport using iodine as the transport reagent. Structural characterization by powder x-ray diffraction confirmed t…

Proximate spin-liquid behavior in the double trillium lattice antiferromagnet K $_{2}$ Co $_{2}$ (SO $_{4}$ ) $_{3}$

A. Magar, K. Somesh, M. P. Saravanan +6

We report proximate quantum spin liquid behavior in K $_{2}$ Co $_{2}$ (SO $_{4}$ ) $_{3}$ with the magnetic Co $^{2 +}$ ions embedded on a highly frustrated three-dimensional double trillium latti…

Pressure-tuned spin chains in brochantite, Cu $_{4}$ SO $_{4}$ (OH) $_{6}$

Victoria A. Ginga, Bin Shen, Ece Uykur +3

Using high-pressure single-crystal x-ray diffraction combined with thermodynamic measurements and density-functional calculations, we uncover the microscopic magnetic model of the…

Pressure-induced strange metal phase in a metallic kagome ferromagnet

Bin Shen, Feng Du, Franziska Breitner +4

Strange metallicity with $T$ -linear electrical resistance preceding high- $T_{c}$ superconductivity remains an enigmatic, yet crucial, signature of correlation physics. Using electric…
