Fast-ion Nb implantation shifts the minimum of the longitudinal magnetoresistance in Cd3As2 thin films from about 4 T to 7 T or beyond 9 T, more than doubling its magnitude.
In the longitudinal setup, all samples exhibit a pronounced NLMR, a known transport signature of the ABJ chiral anomaly [ 4, 5, 22, 33], exceeding −1% as shown in Fig

Tuning chiral anomaly signature in a Dirac semimetal via fast-ion implantation
Fast-ion Nb implantation shifts the minimum of the longitudinal magnetoresistance in Cd3As2 thin films from about 4 T to 7 T or beyond 9 T, more than doubling its magnitude.
