“…В композитах [9] содержание компонентов MnAs (47 mol.%) и Cd 3 As 2 в их эвтектике примерно равное, но в указанной работе не называется концентрация растворенного в Cd 3 As 2 марганца. Между тем, согласно [52,53], соединение Mn 3 As 2 не обладает той же структурой, что α-Cd 3 As 2 . Это означает, что нет непрерывного перехода между α-Cd 3 As 2 и Mn 3 As 2 и существует предел растворимости марганца в арсениде кадмия.…”

“…Т. е. мелкие частицы MnAs, имеющие температуру плавления ниже температуры плавления арсенида кадмия при затвердевании эвтектики не образуются. Вследствие существования зависимости температуры плавления наночастиц от их размера и относительной близости температуры синтеза (1023 K) к температурам плавления массивных Cd 3 As 2 (994 K), MnAs (1208 K) и их эвтектики, в жидкой фазе устанавливается равновесие между количеством растворенного в Cd 3 As 2 марганца и каплями MnAs, размер и количество которых также определяется конкуренцией поверхностной энергии и теплотой плавления наночастицы [52]. Такой механизм, по сути, подтверждается результатами работы [9].…”

The behavior of the manganese impurity in the 3D Dirac semimetal Cd3As2 has been studied by EPR and electromagnetic measurements. It was found that, in contrast to doping with europium, doping with manganese, as well as with iron, does not lead to a change in the sign of the magnetoresistance, which is almost completely suppressed at high manganese concentrations. In this case, a change in the type of the influence of the magnetic field on the contact potential is manifested. The g-factors measured in EPR coincide with the g-factor of a free electron at all temperatures, which, taking into account the fluctuation behavior of the EPR linewidth and the reduced magnetic moment on Mn2 +, indicates the formation of short-lived bound states of the Mn2 + ion and conduction electrons - antiferromagnetic polarons.

“…Studies of the structure and magnetic properties of Mn 3 As 2 are presented in Refs. [13][14][15]. The importance of studying the properties of the diluted magnetic semiconductor (Zn 1-x Mn x ) 3 As 2 induced the study of the quasi-binary system Zn 3 As 2 -Mn 3 As 2 [16].…”

“…Yuzuri reported Cr 3 As 2 to be ferrimagnetic with a tetragonal structure based on X‐ray diffraction, but a separate X‐ray diffraction study by Watanabe et al found Cr 3 As 2 to have a cubic structure; spatial coordinates of the atoms have not been reported for either structure. Mn 3 As 2 has been reported in both orthorhombic and monoclinic structures, as well as a high‐temperature, monoclinic Mn 2.896 As 2 phase above ∼750 K . Some samples with compositions loaded as Mn x As, x > 2, showed weak ferromagnetism that was attributed to Mn 3 As 2 contamination, but the structural assignment of the Mn 3 As 2 phase in those samples was not determined …”

Magnetic ordering and metal‐atom site preference in tetragonal CrMnAs: Electronic correlation effects

2018

The electronic and magnetic structures of tetragonal, Cu Sb-type CrMnAs were examined using density functional theory. To obtain reasonable agreement with reported atomic and low-temperature magnetic ordering in this compound, the intra-atomic electron-electron correlation in term of Hubbard U on Mn atoms are necessary. Using GGA + U, calculations identify four low-energy antiferromagnetically ordered structures, all of which adopt a magnetic unit cell that contains the same direct CrCr and CrMn magnetic interaction, as well as the same indirect Mn⋅⋅⋅Mn magnetic interaction across the Cr planes. One of these low-energy configurations corresponds to the reported case. Effective exchange parameters for metal-metal contacts obtained from SPRKKR calculations indicate both direct and indirect exchange couplings play important roles in tetragonal CrMnAs. © 2018 Wiley Periodicals, Inc.
