Abstract

The structural and magnetic properties of dilutely doped 3d elements in pulsed laser deposition (PLD) grown HfO ₂ high-k dielectric thin films were studied. Monoclinc phase of HfO ₂ was stabilized by Co- and Fe- substitution at significantly low growth temperature. High purity HfO ₂, CoO and Fe ₂O ₃ powders were mixed throughly in the required ratio for 5mol% Co and Fe doping in HfO ₂. The results from atomic force microscopy showed possible segregation of Fe ₃O ₄ phase in the form of nanoscale mounds.
