Influence of substrate on the magnetic properties of Ni and permalloy sub-micrometric patterned stripes

The magnetic properties of sub-micrometric magnetic structures of Ni and permalloy (Ni80Fe20) patterned stripes are studied as functions of temperature. The samples are produced by combining an interferometric lithographic technique with sputtering. At room temperature, ferromagnetic resonance and hysteresis data indicate the existence of an in-plane uniaxial anisotropy in both samples. The NiFe sample has an easy axis along the stripes direction in the entire studied temperature range (2
