Field-induced quantum phase in a frustrated zigzag-square lattice
Hironori Yamaguchi, Kazutoshi Shimamura, Yasuo Yoshida +10
This study presents the experimental realization of a spin-1/2 zigzag-square lattice in a verdazyl-based complex, namely (-Py-V-2,6-F)Cu(hfac). Molecular orbital cal…
Phase Diagram and Soliton Picture of an Ideal Spin-Peierls Compound D-FPNN
Yuji Inagaki, Tatsuya Kawae, Naoko Sakai +10
We investigate magnetic properties of an =1/2 quasi-one dimensional organic antiferromagnet, D-FPNN using magnetization measurements taken at temperatures as low as 0.5 K.…
Atomic-scale visualization of surface-assisted orbital order
Howon Kim, Yasuo Yoshida, Chi-Cheng Lee +6
Orbital-related physics attracts growing interest in condensed matter research, but direct real-space access of the orbital degree of freedom is challenging. Here we report a first…
Magnetic field induced quantum phase transition of the antiferromagnet
S. Nellutla, M. Pati, Y. -J. Jo +11
The magnetic properties of alkali-metal peroxychromate KNaCrO are governed by the pentavalent chromium cation, Cr. Specific heat, magnetocalorimetry, ac ma…
Cascade of magnetic-field-induced quantum phase transitions in a spin triangular-lattice antiferromagnet
N. A. Fortune, S. T. Hannahs, Y. Yoshida +4
We report magnetocaloric and magnetic-torque evidence that in CsCuBr -- a geometrically frustrated Heisenberg triangular-lattice antiferromagnet -- quantum fluc…
Magnetic Field versus Temperature Phase Diagram of the Spin-1/2 Alternating Chain Compound F5PNN
Yasuo Yoshida, Tatsuya Kawae, Yuko Hosokoshi +5
