Phonon spectrum of PrZrO and PrIrO as an evidence of coupling of the lattice with electronic and magnetic degrees of freedom
Yuanyuan Xu, Huiyuan Man, Nan Tang +5
Magnetic materials with pyrochlore crystal structure form exotic magnetic states due to the high lattice frustration. In this work we follow the effects of coupling of the lattice…
Importance of dynamic lattice effects for crystal field excitations in quantum spin ice candidate PrZrO
Yuanyuan Xu, Huiyuan Man, Nan Tang +5
PrZrO is a pyrochlore quantum spin-ice candidate. Using Raman scattering spectroscopy we probe crystal electric field excitations of Pr, and demonstrate the impo…
Low Energy Magneto-optics of TbTiO in [111] Magnetic Field
Xinshu Zhang, Yi Luo, T. Halloran +4
The pyrochlore magnet TbTiO shows a lack of magnetic order to low temperatures and is considered to be a quantum spin liquid candidate. We perform time-domain THz…
Spin-orbital liquid in BaCuSbO stabilized by oxygen holes
Kou Takubo, Takashi Mizokawa, Huiyuan Man +7
Both the Jahn-Teller distortion of CuO octahedra and magnetic ordering are absent in hexagonal BaCuSbO suggesting a Cu 3 spin-orbital liquid state. Here,…
Spin-Orbital Entangled Liquid State in the Copper Oxide BaCuSbO
Huiyuan Man, Mario Halim, Hiroshi Sawa +3
Structure with orbital degeneracy is unstable toward spontaneous distortion. Such orbital correlation usually has a much higher energy scale than spins, and therefore, magnetic tra…
Li1.1(Zn1-xCrx)As: Cr doped I-II-V Diluted Magnetic Semiconductors in Bulk Form

We report the synthesis and characterization of bulk form diluted magnetic semiconductors I-II-V Li1.1(Zn1-xCrx)As (x = 0.03, 0.05, 0.10, 0.15)with a cubic crystal structure identi…
Ba(Zn1-2xMnxCox)2As2: A Bulk Form Diluted Magnetic Semiconductor with n-type Carriers
Huiyuan Man, Cui Ding, Shengli Guo +6
We report the synthesis and characterization of bulk form diluted magnetic semiconductors Ba(Zn1-2xMnxCox)2As2 (0 <= x <= 0.15) with a crystal structure identical to that of 122-ty…
(Sr3La2O5)(Zn1-xMnx)2As2: A Bulk Form Diluted Magnetic Semiconductor isostructural to the "32522" Fe-based Superconductors
Huiyuan Man, Chuan Qin, Cui Ding +6
A new diluted magnetic semiconductor system, (Sr3La2O5)(Zn1-xMnx)2As2, has been synthesized and characterized. 10% Mn substitution for Zn in bulk form (Sr3La2O5)Zn2As2 results in a…
The synthesis and characterization of 1111-type diluted magnetic semiconductors (La1-xSrx)(Zn1-xTMx)AsO (TM = Mn, Fe, Co)
Jicai Lu, Huiyuan Man, Cui Ding +9
The doping effect of Sr and transition metals Mn, Fe, Co into the direct-gap semiconductor LaZnAsO has been investigated. Our results indicate that the single phase ZrCuSiAs-type t…
NMR Investigation of the Diluted Magnetic Semiconductor Li(Zn1-xMnx)P (x = 0.1)
