Cluster-based Haldane state in edge-shared tetrahedral spin-cluster chain: Fedotovite K $_{2}$ Cu $_{3}$ O(SO $_{4}$ ) $_{3}$

M. Fujihala, T. Sugimoto, T. Tohyama +13

Fedotovite K $_{2}$ Cu $_{3}$ O(SO $_{4}$ ) $_{3}$ is a candidate of new quantum spin systems, in which the edge-shared tetrahedral (EST) spin-clusters consisting of Cu $^{2 +}$ are connected by we…

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…

Modified Cross-Correlation for Efficient White-Beam Inelastic Neutron Scattering Spectroscopy

K. Tomiyasu, M. Matsuura, H. Kimura +7

We describe a method of white-beam inelastic neutron scattering for improved measurement efficiency. The method consists of matrix inversion and selective extraction. The former is…

Molecular spin-orbit excitations in the J_eff = 1/2 frustrated spinel GeCo $_{2}$ O $_{4}$

K. Tomiyasu, M. K. Crawford, D. T. Adroja +9

We describe powder and single-crystal inelastic neutron scattering experiments on a spinel-type antiferromagnet GeCo $_{2}$ O $_{4}$ , represented by an effective total angular momentum J_…
