Absence of $μ$ SR evidence for magnetic order in the pseudogap phase of Bi $_{2 + x}$ Sr $_{2 - x}$ CaCu $_{2}$ O $_{8 + δ}$

S. Gheidi, K. Akintola, A. C. Y. Fang +5

We present an extended zero-field muon spin relaxation (ZF- $μ$ SR) study of overdoped Bi $_{2 + x}$ Sr $_{2 - x}$ CaCu $_{2}$ O $_{8 + δ}$ (Bi2212) single crystals, intended to elucidate the origi…

Observation of a charge-neutral muon-polaron complex in antiferromagnetic Cr $_{2}$ O $_{3}$

M. H. Dehn, J. K. Shenton, S. Holenstein +13

We report a comprehensive muon spin rotation ( $μ$ SR) study of the prototypical magnetoelectric antiferromagnet Cr $_{2}$ O $_{3}$ . We find the positively charged muon ( $μ^{+}$ ) occupies sev…

Freezing out of a low-energy bulk spin exciton in SmB6

K. Akintola, A. Pal, S. R. Dunsiger +6

The Kondo insulator SmB6 is purported to develop into a robust topological insulator at low temperature. Yet there are several puzzling and unexplained physical properties of the i…
