Orbital-ordered ferromagnetic insulating state in tensile-strained SrCoO thin films
Sheng-Chieh Huang, Kanchan Sarkar, Renata M. Wentzcovitch +1
At ambient pressure, bulk SrCoO is a ferromagnetic (FM) metal in cubic perovskite structure. By contrast, magnetic properties of epitaxial SrCoO thin films, especially…
Structural transition and re-emergence of iron's total electron spin in (Mg,Fe)O at ultrahigh pressure
Han Hsu, Koichiro Umemoto
Fe-bearing MgO [(MgFe)O] is considered a major constituent of terrestrial exoplanets. Crystallizing in the B1 structure in the Earth's lower mantle, (MgFe)O…
Anomalous thermal properties and spin crossover of ferromagnesite (Mg,Fe)CO3
Han Hsu, Christian P. Crisostomo, Wenzhong Wang +1
Ferromagnesite (Mg,Fe)CO3, also referred to as magnesiosiderite at high iron concentration, is a solid solution of magnesite (MgCO3) and siderite (FeCO3). Ferromagnesite is believe…
Optical signatures of low spin Fe3+: a new probe for the spin state of bridgmanite and post-perovskite
Sergey S. Lobanov, Han Hsu, Jung-Fu Lin +2
Iron spin transition directly affects properties of lower mantle minerals and can thus alter geophysical and geochemical characteristics of the deep Earth. While the spin transitio…
Theoretical prediction of magnetic and noncentrosymmetric Weyl fermion semimetal states in the R-Al-X family of compounds (R=rare earth, Al=aluminium, X=Si, Ge)
Guoqing Chang, Bahadur Singh, Su-Yang Xu +18
Weyl semimetals are novel topological conductors that host Weyl fermions as emergent quasiparticles. While the Weyl fermions in high-energy physics are strictly defined as the mass…
Thermoelasticity of Fe2+-bearing bridgmanite
Gaurav Shukla, Zhongqing Wu, Han Hsu +3
We present LDA+U calculations of high temperature elastic properties of bridgmanite with composition (MgFe)SiO for . Results of elastic mo…
First-principles study of intermediate-spin ferrous iron in the Earth's lower mantle
Han Hsu, Renata M. Wentzcovitch
Spin crossover of iron is of central importance in solid Earth geophysics. It impacts all physical properties of minerals that altogether constitute vol\% of the Earth's…
Ferromagnetic insulating state in tensile-strained LaCoO thin films
Han Hsu, Peter Blaha, Renata M. Wentzcovitch
With local density approximation + Hubbard (LDA+) calculations, we show that the ferromagnetic (FM) insulating state observed in tensile-strained LaCoO epitaxial thin fi…
Spin-state crossover and hyperfine interactions of ferric iron in MgSiO perovskite
Han Hsu, Peter Blaha, Matteo Cococcioni +1
Using density functional theory plus Hubbard calculations, we show that the ground state of (Mg,Fe)(Si,Fe)O perovskite, a major mineral phase in the Earth's lower mantle, h…
