Positron annihilation spectroscopic studies of ferromagnetic methylammonium lead iodide perovskite
Point defects in methylammonium lead iodide (MAPbI3) are believed to be the source of its
room-temperature ferromagnetic behavior. The existence of room-temperature …

A study of Cr3+-substitution induced defects restructuring in BiFeO3 by positron annihilation and other supportive methods
The effects of Cr 3+ ion substitution in place of Fe 3+ ions in BiFe 1-x Cr x O 3
nanocrystallites are reported in this work. Due to the smaller radii of Cr 3+ ions, the …

A modified set-up to reduce background spectra in the CDBS positron spectrometer
M Ghasemifard, M Ghamari - The European Physical Journal Plus, 2021 - Springer
In this study, new methods of unwanted gamma-ray (γ-ray), which reduce the background of
CDBS, were used. In this modified spectroscopic method, after the positron enters the …
