Research Experience

2017 - present

Exotic charge mobility of (Li_1-xFe_x)OHFe_1-ySe films, IOP, CAS, Beijing, China.

For the first time, we have systematically studied the magnetoresistivity and Hall effect in that system, revealing that both electron and hole carriers contribute to transport, whose mobilities become divergent upon T_c and electron moves faster than hole. Ref.: Y.L. Huang et al, arXiv: 1711.02920 (2017)

2015 – 2017

Matrix-assisted hydrothermal epitaxial growth of (Li_1-xFe_x)OHFe_1-ySe films, IOP, CAS, Beijing, China.

We spent 2 years in inventing the film technique, and successfully for the first time synthesized the superconducting (Li,Fe)OHFeSe film of high quality and high critical parameters. The MAHEG method is the sole route to that film so far. Ref.: Y.L. Huang et al, Chin. Phys. Lett. 34 (2017) 077404 (Express Letter). Y.L. Huang et al, arXiv: 1711.02920 (2017)

2015

Delicate magnetic properties based on MPMS-XL1 system with a remanent field less than 4 mOe, IOP, CAS, Beijing, China.        

I performed the delicate magentic measurements of a biocompass protein found in a pigeon retina, and observed a ferrimagnetic hysteresis. That's the first ferrimagnetic identification in an animal magnetoreception protein. Ref. : S.Y. Qin, H. Yin, C.L. Yang, Y.F. Dou, Z.M. Liu, P. Zhang, H. Yu, Y.L. Huang, et al., Nat. Mater. 15, 217–226 (2016)

2014 – 2016

Hydrothermal ion-exchange syntheses of large (Li_1-xFe_x)OHFe_1-ySe crystals, IOP, CAS, Beijing, China.

The most efficient way so far to obtain the single-crystal samples has already recognized and adopted by the superconductivity community. I have tuned the T_c of (Li_1-xFe_x)OHFe_1-ySe from 41 K to zero. Ref. : X.L. Dong, K. Jin, DN. Yuan, H.X. Zhou, J. Yuan, Y.L. Huang, et al., PRB 92, 064515 (2015); Y.L. Huang, et al., unpublished.
