The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator (LS) detector for neutrino mass ordering and other physics research. uses large-size $20$ inches photomultiplier tubes to detect photons from scintillator. PMTs are sensitive easily affected such that the detection efficiency loses about 60$\%$ under geomagnetic field intensity ($\sim$500 mG). It has significant...

We study Ni 80 Fe 20-based permalloys with the relativistic spin-polarized Korringa-Kohn-Rostoker electronic structure method. Treating the compositional disorder with the coherent potential approximation, we investigate how the magnetocrys-talline anisotropy, K, and magnetostriction, λ, of Ni-rich Ni-Fe alloys vary with the addition of small amounts of non-magnetic transition metals, Cu and Mo...
