Observation of the novel type of ordering: Spontaneous ferriquadrupolar order

, 2018
Using Raman and infrared spectroscopies the spontaneous ferriquadrupolar ordering has been observed in the rare-earth-based system KDy(MoO$_4$)$_2$. Ordered quadrupoles in the electron subsystem attend non-equivalent distortions of rare-earth ions in the

Adsorption of rare earth elements in regolith-hosted clay deposits

Nature Communications, 2020
Global resources of heavy Rare Earth Elements (REE) are dominantly sourced from Chinese regolith-hosted ion-adsorption deposits in which the REE are inferred to be weakly adsorbed onto clay minerals.

Implications and Challenges of China’s Supremacy on the Global Rare Earths Market [PDF]

Global Economic Observer, 2021
China’s spectacular economic development over the last four decades or so, and its atypical evolution during this process placed the country both at the forefront of the global rare earth trade, and at the centre of international concerns and debates on ...

An analysis on chain characteristics of highstand geological disasters in high mountains and extremely high mountains based on optical remote sensing technology:A case study of representative large landslides in upper reach of Jinsha River

Zhongguo dizhi zaihai yu fangzhi xuebao, 2021
The upper reaches of Jinsha River are typical high mountain canyon areas with strong terrain cutting and deep valleys. Affected by the Jinsha River fault zone, the slope integrity is poor and the rock mass is fragmented, which makes the mountain ...

Single crystal growth of the pyrochlores $R_2$Ti$_2$O$_7$ ($R$ = rare earth) by the optical floating-zone method

, 2013
We report a systematic study on the crystal growth of the rare-earth titanates $R_2$Ti$_2$O$_7$ ($R$ = Gd, Tb, Dy, Ho, Y, Er, Yb and Lu) and Y-doped Tb$_{2-x}$Y$_x$Ti$_2$O$_7$ ($x$ = 0.2 and 1) using an optical floating-zone method.

Anisotropic electrical and thermal magnetotransport in the magnetic semimetal GdPtBi

, 2020
The half-Heusler rare-earth intermetallic GdPtBi has recently gained attention due to peculiar magnetotransport phenomena that have been associated with the possible existence of Weyl fermions, thought to arise from the crossings of spin-split conduction
