Shape effect in FMR of Ni-Co-Mn-In layers obtained by pulsed laser deposition

We have studied thin layers of Ni50-x Cox Mn50-y Iny alloys on (001) Si substrate obtained by pulsed laser deposition method (PLD) using YAG Nd3+ laser operating at second harmonic. The target was bulk Ni50-x Cox Mn50-y Iny (x = 5, y = 14.5) alloy prepared by induction melting of pure elements under argon atmosphere. Magnetic properties were investigated on Bruker X band EPR spectrometer (9.36 GHz) at room temperature. The magnetic resonance spectrum consists of non-symmetric lines with resonance field within wide field range (2500-4800 Gs) depending on the orientation of the static field in the plane perpendicular to the layer. Calculated spectroscopic splitting factor g = 2.09.
