Figure (a–d) Tunable asymmetric Hall loops at 5 K (magnetic histories are shown in insets). (e) Symmetric loops under high enough external magnetic field. (f) Sketch of the influence of positively ...
With copper-substituted lead apatite below room temperature, Chinese researchers observe diamagnetic dc magnetization under magnetic field of 25 Oe with remarkable bifurcation between ...
Dielectric materials be categorized into four types depending on the hysteresis loops they exhibit: paraelectric (PE), ferroelectric (FE), relaxor ferroelectric (RFE), and antiferroelectric (AFE).
The main researchers working on LK99-like room temperature and room pressure superconductors are in China and South Korea. There have been reports that the China researchers have successfully ...
