Charge Density Modulation and Defect Ordering in Na${}_x$MnBi${}_y$ magnetic semimetal

Aaron Wegner, Despina Louca, Keith Taddei +1

The I-Mn-V antiferromagnet, NaMnBi, develops a very large positive magnetoresistance (MR) up to 10,000% at 2 K and 9 T in crystals showing a semiconductor-to-metal transition (SMT)…
