Monitoring superparamagnetic Langevin behavior of individual $\mathrm{SrRu}{\mathrm{O}}_3$ nanostructures

Omer Sinwani, James W. Reiner, Lior Klein

Patterned nanostructures on the order of 200 nm $\times$ 200 nm of the itinerant ferromagnet $\mathrm{SrRu}{\mathrm{O}}_3$ give rise to superparamagnetic behavior below the Curie temperature (${…
