Abstract:

The magnetic properties and magnetic structure of the quasi-ternary layered intermetallic Y(Mn1-xVx)2Si2 and La(Mn1-xVx)2Si2 (0 ≤ x ≤ 0.4) compounds were investigated using magnetic neutronography, magnetic measurements, and measurements of the thermal expansion coefficient. With increasing content of vanadium, the lattice parameter a remains virtually unchanged, while the parameter c and the unit cell volume increase monotonically. With increasing content of vanadium in the La(Mn1-xVx)2Si2 compounds, weakening of the intralayer ferromagnetic Mn-Mn exchange interactions occurs, which results in an increase in the opening angle of the canted ferromagnetic structure. In the Y(Mn1-xVx)2Si2 compounds, the molecular field of the interlayer Mn-Mn exchange interactions does not change with increasing content of vanadium despite an increase in the interlayer distance and a decrease in the intralayer Mn-Mn exchange interactions which can be considered as the new argument in favor of the fact that the interlayer Mn-Mn exchange interactions in the compounds of the RMn2X2 type are determined by the distance between the manganese atoms within a layer.
