Quantum oscillations of the magnetic properties in Mn-diluted (Mn, Ga)4C alloys
Source abstract
Abstract
High purity antiperovskite-type Mn3−xGa1+xC (0 < x ≤ 0.3) alloys with varied Mn-concentration were prepared by using the solid state reaction method. The Curie temperature and the magnetization of Mn3−xGa1+xC were observed to oscillate as a function of x. The oscillations of the magnetic properties were ascribed to the increasing distance between Mn–Mn atoms due to dilution of the Mn atoms in the Mn3−xGa1+xC lattice with increasing x and the oscillation of the lattice parameters. The period of the oscillations in the current Mn-diluted alloys is much smaller than that observed in magnetic films, indicating fundamentally different mechanisms from the traditional oscillations of physical observables as a function of inverse magnetic field in metals/semi-metals/insulators or as a function of thickness of magnetic/nonmagnetic layer in multilayered magnetic films. This work opens new perspectives for the oscillations of physical observables in novel magnetic materials.
