Research output: Contribution to journalArticlepeer-review


CaRuO3 is a paramagnetic metal and since its low temperature resistivity is described by ρ=ρ0+ATγ with γ∼1.5, it is also considered a non-Fermi liquid (NFL) metal. We have performed extensive magnetoresistance and Hall effect measurements of untwinned epitaxial films of CaRuO3. These measurements reveal that CaRuO3 exhibits uniaxial magnetocrystalline anisotropy. In addition, the low-temperature NFL behavior is most effectively suppressed when a magnetic field is applied along the easy axis, suggesting that critical spin fluctuations, possibly due to proximity of a quantum critical phase transition, are related to the NFL behavior.
