Suppression of orbital ordering and emergence of a glassy magnetic state in a high-entropy spinel vanadate

Shun Ito, Sota Nakakuki, Satoshi Demura +1

High-entropy oxides provide a unique platform for exploring the interplay between configurational disorder and correlated electronic states. We report on structural, thermodynamic,…

Magnetoelastic effects in the metallic frustrated antiferromagnet CrB $_{2}$

Tadataka Watanabe, Mai Watanabe, Sakurako Suganuma +2

Hexagonal chromium diboride CrB $_{2}$ is a metallic frustrated antiferromagnet with a Néel temperature $T_{N} \sim$ 88 K. In CrB $_{2}$ , Cr 3 $d$ electrons not only give rise to localized…

Emergence of highly degenerate excited states in frustrated magnet MgCr $_{2}$ O $_{4}$

K. Tomiyasu, T. Yokobori, Y. Kousaka +5

High degeneracy in ground states leads to the generation of exotic zero-energy modes, a representative example of which is the formation of molecular spin liquid-like fluctuations…
