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…

Three superconducting phases with different categories of pairing in hole- and electron-doped LaFeAs $_{1 - x}$ P $_{x}$ O

S. Miyasaka, M. Uekubo, H. Tsuji +8

The phase diagram of LaFeAs $_{1 - x}$ P $_{x}$ O system has been extensively studied through hole- and electron-doping as well as As/P-substitution. It has been revealed that there are th…

Tomonaga-Luttinger spin liquid in the spin-1/2 inequilateral diamond-chain compound K $_{3}$ Cu $_{3}$ AlO $_{2}$ (SO $_{4}$ ) $_{4}$

M. Fujihala, H. Koorikawa, S. Mitsuda +14

K $_{3}$ Cu $_{3}$ AlO $_{2}$ (SO $_{4}$ ) $_{4}$ is a highly one-dimensional spin-1/2 inequilateral diamond-chain antiferromagnet. Spinon continuum and spin-singlet dimer excitations are observed in…

Absence of magnetic long range order in Ba $_{3}$ ZnRu $_{2}$ O $_{9}$ : A spin-liquid candidate in the $S = 3/2$ dimer lattice

Ichiro Terasaki, Taichi Igarashi, Takayuki Nagai +12

We have discovered a novel candidate for a spin liquid state in a ruthenium oxide composed of dimers of $S =$ 3/2 spins of Ru $^{5 +}$ ,Ba $_{3}$ ZnRu $_{2}$ O $_{9}$ . This compound lacks a lon…
