Manifestations of multiple-carrier charge transport in the magnetostructurally ordered phase of undoped BaFe $_{2}$ As $_{2}$

S. Ishida, T. Liang, M. Nakajima +10

We investigated the transport properties of BaFe $_{2}$ As $_{2}$ single crystals before and after annealing with BaAs powder. The annealing remarkably improves transport properties, in p…

Order by quenched disorder in the model triangular antiferromagnet RbFe(MoO4)2

A. I. Smirnov, T. A. Soldatov, O. A. Petrenko +5

We observe a disappearance of the 1/3 magnetization plateau and a striking change of the magnetic configuration under a moderate doping of the model triangular antiferromagnet RbFe…

Mobility spectrum analytical approach for intrinsic band picture of Ba(FeAs) $_{2}$

Khuong Kim Huynh, Yoichi Tanabe, Takahiko Urata +4

Unconventional high temperature superconductivity as well as three-dimensional bulk Dirac cone quantum states arising from the unique d-orbital topology has been a recent priority…

Field-induced quantum magnetism in the verdazyl-based charge-transfer salt $[$ $o$ -MePy-V-( $p$ -Br) $_{2}]$ FeCl $_{4}$

Y. Iwasaki, T. Kida, M. Hagiwara +6

We successfully synthesized a verdazyl-based charge-transfer salt $[$ $o$ -MePy-V-( $p$ -Br) $_{2}]$ FeCl $_{4}$ , which has an $S_{V}$ =1/2 on the radical $o$ -MePy-V-( $p$ -Br) $_{2}$ and an $…

Ferrimagnetic spin-1/2 chain of alternating Ising and Heisenberg spins in arbitrarily oriented magnetic field

J. Strecka, M. Hagiwara, Y. Han +3

The ferrimagnetic spin-1/2 chain composed of alternating Ising and Heisenberg spins in an arbitrarily oriented magnetic field is exactly solved using the spin-rotation transformati…

Spontaneous magnetic field and disorder effects in BaPtAs_1-x_Sb_x_ with honeycomb network

T. Adachi, T. Ogawa, Y. Komiyama +21

Chiral superconductivity exhibits the formation of novel electron pairs that breaks the time-reversal symmetry and has been actively studied in various quantum materials in recent…
