Elastic softness of low-symmetry frustrated TiO ( = Co, Fe)
Tadataka Watanabe, Kazuya Takayanagi, Ray Nishimura +4
Orthorhombic pseudobrookites CoTiO and FeTiO have a low-symmetry crystal structure comprising magnetic Co/Fe ions and nonmagnetic Ti ions, wher…
Quantum spin state stabilized by coupling with classical spins
Hironori Yamaguchi, Tsuyoshi Okubo, Akira Matsuo +5
We introduce a model compound featuring a spin-1/2 frustrated square lattice partially coupled by spin-5/2. A significant magnetization plateau exceeding 60 T could be observed, in…
Fingerprints of Mott and Slater gaps in the core-level photoemission spectra of antiferromagnetic iridates
K. Nakagawa, A. Hariki, T. Okauchi +15
We present Ir core-level hard-x-ray photoemission spectroscopy (HAXPES) experiments conducted across antiferromagnetic (AFM) ordering transition in Ruddlesden-Popper iridates…
Magnetic properties of a spin-1/2 octagonal lattice
Satoshi Morota, Takanori Kida, Masayuki Hagiwara +3
We successfully synthesized a verdazyl-based complex, (-Py-V--CN)[Cu(hfac)]. Molecular orbital calculations reveal that three types of antiferromagnetic (AF) interact…
