dc.descriptionThe magnetic penetration depth $λ(0)$ in polycrystalline MgB$_{2}$ for different boron isotopes ($^{10}$B/$^{11}$B) was investigated by transverse field muon spin rotation. No boron isotope effect on the penetration depth $λ(0)$ was found within experimental error: $Δλ(0)/λ(0) = -0.8(8)%$, suggesting that MgB$_{2}$ is an adiabatic superconductor. This is in contrast to the substantial oxygen isotope effect on $λ(0)$ observed in cuprate high-temperature superconductors.
