Magnetic Ordering of Ammonium Cations in NHI, NHBr and NHCl
Fei Yen, Lei Meng, Tian Gao +1
The different types of magnetism arise mainly from how electrons move and interact with each other. In this work, we show how protons (H) also exhibit magnetic behavior. We mea…
Magnetically-driven structural phase transition in hexamethylbenzene
Fei Yen
The methyl groups in hexamethylbenzene C(CH) become magnetically ordered at the molecular level below 118 K. This is also near the temperature at which the system struc…
Isotope Effect on the Magnetic Properties of Hexamethylbenzene: Evidence of Magnetism Based on Correlated Motion of Deuterons
Fei Yen
The associated magnetic moments of the periodic rotational motion of methyl groups in hexamethylbenzene C(CH) were recently identified to contribute to its overall magn…
Possible magnetism based on orbital motion of protons in ice
Fei Yen, Tian Gao, Yongsheng Liu +1
A peak anomaly is observed in the magnetic susceptibility as a function of temperature in solid H2O near Tp=60 K. At external magnetic fields below 2 kOe, Tp becomes positive in th…
Ultrahigh Pressure Superconductivity in Molybdenum Disulfide
Zhenhua Chi, Feihsiang Yen, Feng Peng +9
Superconductivity commonly appears under pressure in charge density wave (CDW)-bearing transition metal dichalcogenides (TMDs), but has emerged so far only via either intercalation…
Proton ordering dynamics of H2O ice
Fei Yen, Zhenhua Chi
From high precision measurements of the complex dielectric constant of H2O ice, we identify the critical temperatures of the phase transition into and out of ice XI from ice Ih to…
