Investigation of Mn‐dimers formation in silicon by SIMS method [PDF]

open access: yesSurface and Interface Analysis, 2008
Abstract It has been theoretically predicted that manganese atoms in silicon matrix tend to form dimers which can show both ferro‐ and antiferromagnetic properties. One might expect that the significant part of such dimers (N‐mers) should be spattered as cluster ions while SIMS measurement.

Geochemistry of beryl varieties: comparative analysis and visualization of analytical data by principal component analysis (PCA) and t-distributed stochastic neighbor embedding (t-SNE)

open access: yesЗаписки Горного института, 2022
A study of the trace element composition of beryl varieties (469 SIMS analyses) was carried out. Red beryls are distinguished by a higher content of Ni, Sc, Mn, Fe, Ti, Cs, Rb, K, and B and lower content of Na and water.
