Quantum Oscillations in Noncentrosymmetric Weyl Semimetal SmAlSi
文献摘要：
As a new type of quantum state of matter hosting low energy relativistic quasiparticles,Weyl semimetals(WSMs)have attracted significant attention for scientific community and potential quantum device applications.In this study,we present a comprehensive investigation of the structural,magnetic,and transport properties of noncentrosymmetric RRAlSi(R=Sm,Ce),which have been predicted to be new magnetic WSM candidates.Both samples exhibit nonsaturated magnetoresistance,with about 900％and 80％for SmAlSi and CeAlSi,respectively,at temperature of 1.8 K and magnetic field of 9T.The carrier densities of SmAlSi and CeAlSi exhibit remarkable change around magnetic transition temperatures,signifying that the electronic states are sensitive to the magnetic ordering of rare-earth elements.At low temperatures,SmAlSi reveals prominent Shubnikov-de Haas oscillations associated with the nontrivial Berry phase.High-pressure experiments demonstrate that the magnetic order is robust and survival under high pressure.Our results would yield valuable insights into WSM physics and potentials in applications to next-generation spintronic devices in the RAlSi(R=Sm,Ce)family.
