Structure and composition of layers of Ni-Co-Mn-In Heusler alloys obtained by pulsed laser deposition

Abstract

In present work we were analysing thin layers of Ni-Co-Mn-In alloys, grown by pulsed laser deposition method (PLD) on Si, NaCl and glass substrates. For target ablation the second harmonics of YAG:Nd3+ laser was used. The target had the composition Ni45Co5Mn34.5In14.5. The morphology of the layers and composition were studied by electron microscopy TESCAN Vega3 equipped with microanalyzer EDS – Easy EdX system working with Esprit Bruker software. The X-ray diffraction measurements (XRD), performed on spectrometer Bruker XRD D8 Advance system, reveals Ni2-Mn-In cubic phase having lattice constant a = 6.02Å.
