Piezomagnetic effect of a rare-earth-based altermagnet TbPt6Al3

Ryohei Oishi, Kazunori Umeo, Takuya Aoyama +2

We have investigated the piezomagnetic (PZM) effect of the rare-earth-based g-wave altermagnet TbPt6Al3 by magnetization measurements of single-crystalline samples under uniaxial s…

Structural Evolution from Hyper-Honeycomb to Honeycomb Networks and Superconductivity in LaPt $_{x}$ Si $_{2 - x}$

Sitaram Ramakrishnan, Tatsuya Yamakawa, Ryohei Oishi +11

We report the crystal structures and superconductivity (SC) of LaPt $_{x}$ Si $_{2 - x}$ ( $0.5 \leq x \leq 1.0$ ) that are solid solutions of LaSi $_{2}$ and LaPtSi with centrosymmetric t…
