Unconventional superconductivity and magnetism in Sr2RuO4 and related materials
We review the normal and superconducting state properties of the unconventional triplet superconductor Sr2RuO4 with an emphasis on the analysis of the magnetic susceptibility and the role played by strong electronic correlations. In particular, we show that the magnetic activity arises from the itinerant electrons in the Ru d-orbitals and a strong magnetic anisotropy occurs (χ+− < χ) due to spi...
متن کاملIntroduction to Unconventional Superconductivity
This lecture gives a basic introduction into some aspects of the unconventional superconductivity. First we analyze the conditions to realize unconventional superconductivity in strongly correlated electron systems. Then an introduction of the generalized BCS theory is given and several key properties of unconventional pairing states are discussed. The phenomenological treatment based on the Gi...
متن کاملThe challenge of unconventional superconductivity.
During the past few decades, several new classes of superconductors have been discovered that do not appear to be related to traditional superconductors. The source of the superconductivity of these materials is likely different from the electron-ion interactions that are at the heart of conventional superconductivity. Developing a rigorous theory for any of these classes of materials has prove...
متن کاملSupporting Online Material “Odd-Parity Superconductivity in Sr2RuO4”
1. Materials and sample preparation High-quality single crystals of Sr2RuO4 used in this work were grown by the floatingzone technique and characterized in detail by standard techniques (S1). We found in the course of this work that crystals with an optimal superconducting transition temperature (Tc) around 1.5 K typically have more Ru inclusions than those with slightly lower Tc. However, thos...
متن کاملThe penetration depth in Sr2RuO4: Evidence for orbital dependent superconductivity
– The apparent T -temperature dependence of the London penetration depth in Sr2RuO4 is discussed on the basis of a multi-gap model with horizontal line nodes. The influence of the nodes in combination with nonlocal electromagnetic response leads to low-temperature behaviors as −T 2 lnT in the London limit and as T 2 in the Pippard limit. These behaviors appear only at very low temperature. On t...
