Ternäre Mangan-Verbindungen AMnX (A ≙ Mg, Ca, Sr oder Ba; X ≙ Si, Ge oder Sn): Neutronenbeugungsuntersuchungen zur Charakterisierung der magnetischen Eigenschaften

2D‐Berry‐Curvature‐Driven Large Anomalous Hall Effect in Layered Topological Nodal‐Line MnAlGe

“…Many ternary Mn‐based compounds such as MgMnGe, CaMnSn, SrMnSn, SrMnGe, CaMnGe, and MnAlGe adopt this structure type. [ 35 ] Except MnAlGe, all of the other mentioned compounds display antiferromagnetic ordering and are semiconductors. MnAlGe is a special example in this class of compounds because it contains an extra valence electron that imparts metallic character and exhibits ferromagnetism at a very high temperature ( T C ≈ 503 K).…”

Zur Abgrenzung der PbFCl- und Cu2Sb-Strukturfamilien: Neubestimmung und Verfeinerung der Kristallstrukturen von CuMgSb, Cu2Sb und CuMgAsProfessor Joachim Strähle zum 65. Geburtstag gewidmet

“…S, Se, Te; B ϭ Zr, Hf) [5,6], UNA2 (A2 ϭ Cl, Br, I) [7], MnA2B (A2 ϭ Mg, Ca, Sr, Ba und B ϭ Si, Ge, Sn) [8], NaMgB (B ϭ As, Sb) [9] und MnA2B (A2 ϭ Na, K; B ϭ P, As, Sb) [10,11] zeigen, zusammen mit strukturchemischen Betrachtungen an ausgewählten Verbindungen [1, 12,13,14], dass sich die Strukturfamilie in zwei Untergruppen einteilen lässt, in denen jeweils verschiedene Anteile ionischer bzw. kovalenter Bindungen wirksam sind.…”

Electronic structure and magnetic properties of RMnX (R = Mg, Ca, Sr, Ba, Y; X = Si, Ge) studied by KKR method

“…from the neutron diffraction data [4,5,8], whereas the atomic coordinates have been taken from the single crystal X-ray diffraction data [16] (Table 2). Noteworthy, for the YMnSi compound, the room temperature lattice parameters have been applied.…”

“…The structural and magnetic properties of the CeFeSitype RMnX (R = La -Tb (or Sm), Y, Mg -Ba) silicides and germanides have been extensively studied during the last decade, especially by means of X-ray diffraction, magnetic measurements, and neutron powder diffraction [1,2,3,4,5,6,7,8,9,10]. The CeFeSi-type structure (Table 1, Fig.…”

“…[5]]. The largest values of the Mn magnetic moment are observed in the compounds characterised by the largest Mn-X and Mn-Mn distances [4,6,7,8].…”
