Bosonic spectrum of a correlated multiband system, BaFe1.80Co0.20As2, obtained via infrared spectroscopy
Chandan Kumar Panda, Hong Gu Lee, Hwiwoo Park +3
We investigated a single crystal BaFe(2-x)CoxAs2 (Co-doped BaFe2As2: Co-doped Ba122) with x = 0.20 using infrared spectroscopy. We obtained the bosonic spectrum from the measured s…
Giant magnetic anisotropy in the atomically thin van der Waals antiferromagnet FePS3
Youjin Lee, Suhan Son, Chaebin Kim +13
Van der Waals (vdW) magnets are an ideal platform for tailoring two-dimensional (2D) magnetism with immense potential for spintronics applications and are intensively investigated.…
Weakness of Correlation Effect Manifestation in BaNiAs: ARPES and LDA+DMFT study
N. S. Pavlov, T. K. Kim, A. Yaresko +3
The electronic spectral function of BaNiAs is investigated using both the angle-resolved photoemission spectroscopy (ARPES) and a combined computational scheme of local den…
Charge-spin correlation in van der Waals antiferromagenet NiPS3
So Yeun Kim, Tae Yun Kim, Luke J. Sandilands +13
Strong charge-spin coupling is found in a layered transition-metal trichalcogenide NiPS3, a van derWaals antiferromagnet, from our study of the electronic structure using several e…
Properties of spin 1/2 triangular lattice antiferromagnets: CuRE2Ge2O8 (RE=Y, La)
Hwanbeom Cho, Marie Kratochvilova, Hasung Sim +10
We found new two-dimensional (2D) quantum (S=1/2) antiferromagnetic systems: CuRE2Ge2O8 (RE=Y and La). According to our analysis of high-resolution X-ray and neutron diffraction ex…
Doping effects on trimerization and magnetoelectric coupling of single crystal multiferroic (Y,Lu)MnO3
Seongil Choi, Hasung Sim, Sunmin Kang +2
Hexagonal RMnO3 is a multiferroic compound with a giant spin-lattice coupling at an antiferromagnetic transition temperature [1]. Despite extensive studies over the past two decade…
Tunneling transport of mono- and few-layers magnetic van der Waals MnPS
Sungmin Lee, Ki-Young Choi, Sangik Lee +2
We have investigated the tunneling transport of mono- and few-layers of MnPS3 by using conductive atomic force microscopy. Due to the band alignment of indium tin oxide/MnPS3/Pt-Ir…
Hidden non-Fermi liquid behavior caused by magnetic phase transition in Ni-doped Ba-122 pnictides
Seokbae Lee, Kiyoung Choi, Eilho Jung +4
We studied two BaFe2-xNixAs2 (Ni-doped Ba-122) single crystals at two dfferent doping levels (underdoped and optimally doped) using an optical spectroscopic technique. The underdop…
Enhanced Upper Critical Fields in a New Quasi-one-dimensional Superconductor Nb2PdxSe5
Seunghyun Khim, Bumsung Lee, Ki-Young Choi +9
We report a discovery of superconductivity with Tc = 5.5 K in Nb2PdxSe5, in which one-dimensional (1D) Nb-Se chains existing along the b-direction hybridize each other to form the…
Existence of Orbital Order and its Fluctuation in Ba(FeCo)As Revealed by X-ray Absorption Spectroscopy
