Tricritical Point Modifications by Magnetic Impurities in an Itinerant Electron Sdw System
نویسندگان
چکیده
The polarization of magnetic impurities by a spin-density-wave tends to stabilize the commensurate SDW phase and to modify the coordinates of the tricritical point. A numerical calculation has been performed to obtain the impurity concentration dependence of the tricritical point coordinates and the associated discontinuity in the SDW wave-vector.

4f-local magnetic moments in the metals and alloys with SDW-instability
2014 The usual interaction between localized magnetic moments and itinerant electrons (RKKY-coupling) is modified by the additional coupling between nesting electrons and hole parts of the Fermi surface. It is shown that the presence of localized magnetic moments of magnetic impurities leads to the appearance of spin-density-waves in the itinerant electron system even in the case where nesting ...
متن کاملQuantum phase transitions of magnetic rotons.
Because of weak spin-orbit coupling and broken inversion symmetry the paramagnons of an itinerant, almost ferromagnetic system become magnetic rotons. Using self-consistent Hartree and renormalization group calculations, we study weak fluctuation-driven first-order quantum phase transitions, a quantum tricritical point controlled by anisotropy, and non-Fermi liquid behavior associated with the ...

In this paper we study the Aharonov-Bohm oscillations of transmission coefficient for an electron passing through a quantum nanoring with two identical magnetic impurities using quantum waveguide theory. It is shown that the Aharonov-Bohm oscillations are independent of the coupling constant between the electron and magnetic impurities for the singlet spin state of impurities, while for the o...
متن کاملInterplay 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 کاملEffect of doping on the pseudogap enhancement due to magnetic impurities in d-density waves
We study the effect of quantum magnetic impurities on d-wave spin density waves (d-SDW). The impurity spins are aligned coherently according to the spin space anisotropy of the condensate. Both the order parameter and transition temperature increases due to the coherent interplay between magnetic scatterers and d-SDW at fixed doping. By increasing the doping, the d-SDW collapses. This can expla...
