“…In short, the FM mainly depends on the concentrations of V O s and Mn ions that are coupled with each other. According to Hund's rule, the spins contributed by an Mn 2+ , an Mn 3+ , and an Mn 4+ ion are 4/2, 5/2, and 4/2, respectively 34,35 . In other words, an Mn 2+ and an Mn 4+ ion provide the same local spin moment, whereas an Mn 3+ ion provides more local spin moment than the other two.…”

Interestingly, GMO-air and GMO-O 2 have approximately the same concentration of Mn 3+ ions and same concentration of total Mn dopants.…”

Mn‐doped β‐Ga2O3 (GMO) films with room‐temperature ferromagnetism (RTFM) are synthesized by polymer‐assisted deposition, and the effects of annealing atmosphere (air or pure O2 gas) on their structures and physical properties are investigated. The characterizations show that the concentrations of vacancy defects and Mn dopants in various valence states and lattice constants of the samples are all modulated by the annealing atmosphere. Notably, the samples annealed in air (GMO–air) exhibit a saturation magnetization as strong as 170% times that of the samples annealed in pure O2 gas (GMO–O2), which can be quantitatively explained by oxygen vacancy (VO)‐controlled ferromagnetism due to bound magnetic polarons established between delocalized hydrogenic electrons of VOs and local magnetic moments of Mn2+, Mn3+, and Mn4+ ions in the samples. Our results provide insights into mechanism‐based tuning of RTFM in Ga2O3 and may be useful for design, fabrication, and application of related spintronic materials.

“…There is no an encountered study with the heteroatomic microclusters containing Mn, Ni, In atoms. In the studies with the Mn clusters the magnetic properties of the clusters have been investigated [22][23][24][25][26][27]. Also, there are studies related with the Mn ions [28][29][30] and diatomic alloys like MnNi, MnIn NiIn in the literature [31][32][33][34].…”

In this study, Ni, Mn and In atoms formed by different combinations of diatoms due to the spin multiplicity of electronic structure characteristics have been investigated. Calculations have been performed by Density Functional Theory within B3LYP functional and CEP-121G basis set. Diatoms with the first five spin multiplicity configurations have been investigated and the most stable state has been determined. The energetics, such as binding energy, frontier molecular orbital energies of six possible diatoms have been calculated in their ground state with their lowest five spin multiplicities.
