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…
Mn-doping induced ferromagnetism and enhanced superconductivity in Bi_4-x Mn_x O_4 S_3 (0.075 < = x < = 0.15)
Zhenjie Feng, Xunqing Yin, Yiming Cao +14
We demonstrate that Mn-doping in the layered sulfides Bi_4O_4S_3 leads to stable Bi_4-x Mn_x O_4 S_3 compounds that exhibit both long-range ferromagnetism and enhanced superconduct…
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…
Dielectric Anomaly in Ice near 20 K; Evidence of Macroscopic Quantum Phenomena
Fei Yen, Tian Gao
H2O is one of the most important substances needed in sustaining life; but yet not much is known about its ground state. Here, a previously unidentified anomaly is identified in th…
Itinerant metamagnetism in manganites caused by the field-induced electronic nematic order
Tian Gao, Shixun Cao, Shujuan Yuan +3
Itinerant metamagnetism transition is observed and studied in perovskite La1-xCaxMn0.90Cu0.10O3 system for x = 0.30. At a constant low temperature, 10 K < T < 150 K, there is a con…
