Quantum criticality in CaRuO3 - Influence of Ti substitution
Апстракт
Thermodynamic and transport properties of the CaRu1xTixO3 system with x?=?0, 0.03, 0.07, 0.10, and 0.15 in magnetic field up to 9?T have been studied. The unconventional temperature dependences of magnetic susceptibility, specific heat, and electrical resistivity observed for CaRuO3 are typical for non-Fermi liquids and they support the assumption about the proximity of the system to the quantum critical point. The analysis of the experimental results suggests the electronic phase separation in CaRuO3 into ferromagnetic itinerant regions coexisting with strongly correlated ones. Substitution by titanium seems to push the system towards ferromagnetism, and drives it away from the quantum criticality.
