Novel coexistence of superconductivity with two distinct magnetic orders.

چکیده
The heavy fermion system exhibits properties that range from an incommensurate antiferromagnet for small to an exotic superconductor on the Ir-rich end of the phase diagram. At intermediate where antiferromagnetism coexists with superconductivity, two types of magnetic order are observed: the incommensurate one of and a new, commensurate antiferromagnetism that orders separately. The coexistence of -electron superconductivity with two distinct -electron magnetic orders is unique among unconventional superconductors, adding a new variety to the usual coexistence found in magnetic superconductors.

Interplay between magnetism and superconductivity in the iron pnictides
We consider phase transitions and potential coexistence of spin-density-wave SDW magnetic order and extended s-wave s+ superconducting order within a two-band itinerant model of iron pnictides in which SDW magnetism and s+ superconductivity are competing orders. We show that depending on parameters, the transition between these two states is either first order or involves an intermediate phase ...

متن کامل1 8 Se p 20 08 Coexistence of Long - Range Magnetic Order and Superconductivity from Campbell Penetration
Application of a tunnel-diode resonator (TDR) technique for studies of the vortex response in magnetic superconductors is described. Operating at very small ex-citation fields and sufficiently high frequency, TDR was used to probe small-amplitude linear AC response in several types of single crystals where long-range magnetic order coexists with bulk superconductivity. Full local-moment ferroma...
متن کاملTailoring phase slip events through magnetic doping in superconductor-ferromagnet composite films
The interplay between superconductivity (SC) and ferromagnetism (FM) when embedded together has attracted unprecedented research interest due to very rare coexistence of these two phenomena. The focus has been mainly put into the proximity induced effects like, coexistence of magnetism and superconductivity, higher critical current, triplet superconductivity etc. However, very little attention ...
متن کاملCoexistence of charge-density-wave and pair-density-wave orders in underdoped cuprates.
We analyze incommensurate charge-density-wave (CDW) and pair-density-wave (PDW) orders with transferred momenta (±Q,0)/(0,±Q) in underdoped cuprates within the spin-fermion model. Both orders appear due to an exchange of spin fluctuations before magnetic order develops. We argue that the ordered state with the lowest energy has nonzero CDW and PDW components with the same momentum. Such a state...
