Itinerant Ferromagnetism and Superconductivity
Superconductivity has again become a challenge following the discovery of unconventional superconductivity. Resistance-free currents have been observed in heavy-fermion materials, organic conductors and copper oxides. The discovery of superconductivity in a single crystal of UGe2, ZrZn2 and URhGe revived the interest in the coexistence of superconductivity and ferromagnetism. The experiments in...
متن کاملSuperconductivity on the border of weak itinerant ferromagnetism in UCoGe.
We report the coexistence of ferromagnetic order and superconductivity in UCoGe at ambient pressure. Magnetization measurements show that UCoGe is a weak ferromagnet with a Curie temperature T(C)=3 K and a small ordered moment m(0)=0.03 micro(B). Superconductivity is observed with a resistive transition temperature T(s)=0.8 K for the best sample. Thermal-expansion and specific-heat measurements...
متن کاملCoexistence of triplet superconductivity and itinerant ferromagnetism
The triplet superconductivity in UGe2 and URhGe coexists with itinerant ferromagnetism such that in the pressuretemperature phase diagram the whole region occupied by the superconducting state is situated inside a more vast ferromagnetic region. In the same family metal UCoGe the pressure dependent critical lines TCurie(P) and Tsc(P) of the ferromagnet and the superconducting phase transitions ...
متن کاملSegmented band mechanism for itinerant ferromagnetism.
We introduce a novel mechanism for itinerant ferromagnetism, which is based on a simple two-band model, and, by using numerical and analytical methods, we show that the periodic Anderson model contains this mechanism. We propose that the mechanism, which does not assume an intra-atomic Hund's coupling, is present in both the iron group and some f electron compounds.
متن کاملSuperconductivity and Quantum Phase Transitions in Weak Itinerant Ferromagnets
It is argued that the phase transition in low-Tc clean itinerant ferromagnets is generically of first order, due to correlation effects that lead to a nonanalytic term in the free energy. A tricritical point separates the line of first order transitions from Heisenberg critical behavior at higher temperatures. Sufficiently strong quenched disorder suppresses the first order transition via the a...
