Abstract

SrRuO 3 is a 4d itinerant ferromagnet. Thin films of SrRuO 3 on SrTiO 3 substrate have Curie temperature of ∼ 150 K and are characterized by extremely large uniaxial anisotropy (H anis ∼ 10 T) with the easy axis at 45° relative to the film normal. We explore local magnetization reversal events in this system by measuring the extraordinary Hall effect in micron-size patterns. With this technique we follow distinct magnetization events and can detect flipping of less than 1% of the probed area which for our samples amounts to ∼2 × 10 7 spins.
