Layered compounds AFBiS2: superior birefringent crystals
Hai Wang
Stimulated by the discovery of the giant birefringence (GBF) in LaOBiS2 (H. Wang, arxiv: 1304.5032), we check SrFBiS2 and find a superior birefringence up to 1.28. Naturally, AF la…
Giant birefringence in layered compound LaOBiS2
Hai Wang
Birefringent crystals (BFC) have been extensively used in imaging spectrometer, laser devices, and optical components. Seeking new BFC is of important for both fundamental research…
Interatomic exchange coupling of BCC iron
Hai Wang, Pui-Wai Ma, C. H. Woo
We performed first-principle calculations on the exchange interaction (EI) between atoms in BCC-Fe strained volumetrically. Our results show that the volume-dependence of the EI de…
Striped-magnetic-order suppresses giant optical anisotropy and drives structural distortion in iron arsenide superconductors
Hai Wang
To examine the role of magnetism in superconductivity of iron-based superconductors, we first present first-principles optical calculations on three representative parent compounds…
Ballistic Magnetoresitance over 4000% at Room Temperature in Ni-Ni Electrodeposited Nanocontacts
Hai Wang, H. Cheng, N. Garcia
This paper reports ballistic magnetoresistance values over 4000% measured in electrodeposited Ni-Ni nanocontacts with T geometry previously developed . Over the time, after several…
