Microscopic dynamics perspective on the relationship between Poisson ratio and ductility of metallic glasses
K. L. Ngai, Li-Min Wang, Riping Liu +1
In metallic glasses a clear correlation had been established between plasticity or ductility with the Poisson ratio and alternatively the ratio of the elastic bulk modulus to the s…
A new class of topological insulators from I-III-IV half-Heusler compounds with strong band inversion strength
X. M. Zhang, G. Z. Xu, Y. Du +4
In this paper, by first principle calculations, we investigate systematically the band topology of a new half-Heusler family with composition of I(A)-III(A)-IV(A). The results clea…
Crossover of magnetoresistance in the zerogap half-metallic Heusler alloy Fe2CoSi
Y. Du, G. Z. Xu, X. M. Zhang +5
This work reports on the band structure and magneto-transport investigations of the inverse Heusler compound Fe2CoSi. The first-principles calculations reveal that Fe2CoSi has a ve…
First-principles investigation of half-metallic ferromagnetism of half-Heusler compounds XYZ
L. Feng, E. K. Liu, W. X. Zhang +2
We investigate the electronic structure and magnetism of half-Heusler compounds XYZ (X, Y=V, Cr, Mn, Fe, Co and Ni; Z=Al, Ga, In, Si, Ge, Sn, P, As, and Sb) using the ab initio den…
Topological Insulators in Hexagonal Wurtzite-type Binary Compounds
X. M. Zhang, R S. Ma, X. C. Liu +5
We propose new topological insulators in hexagonal wurtzite-type binary compounds based on the first principles calculations. It is found that two compounds AgI and AuI are three-d…
Mn-doping induced magnetic properties in Co2CrO4 system
H. G. Zhang, W. H. Wang, E. K. Liu +5
Abundant phenomena in CoCr2-xMnxO4 (x = 0 ~ 2) samples such as magnetic compensation, magnetostriction and exchange bias effect have been observed and investigated in this work. A…
