Structural and magnetic properties of nickel catalyzed-tungsten oxide nanosheets synthesized using e-beam rapid thermal annealing

► Effects of ERTA on Ni-W/Si (100) thin films are discussed. ► Nickel has a catalytic activity on the growth of WOX nanostructures. ► The formation of nanosheets happens in very short time duration. ► Beam current affects the structural and magnetic properties of Ni-W/Si films. ► Thermal stress plays an important role in the sheet formation.
