Abstract: W59.00012 : Quantitative analysis of chiral anomaly induced negative magnetoresistance in nodal-line semimetal SrAs3
. The v is fermi velocity; μ is chemistry potential and τ is scattering time. The τ depends on the magnetic field and temperature. When the magnetic is higher than the quantum limit, the , the NMR will saturate.
Among the predicted nodal-line semimetals, SrAs3 has high mobility and low fermi energy, which makes this material an ideal platform to research the behavior of NMR with magnetic field and temperature. Under 31.5 T, we observed the process from NMR appeared to saturated. And analyzed the behavior of NMR quantitatively. Combined with the result from PPMS, we also got the temperature dependence of τ.
