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 کاملItinerant Ferromagnetism and Quantum Criticality in Sc3In
The electronic structure and magnetic properties of hexagonal Sc3In are calculated within density functional theory. We find that the Fermi energy lies in a region of flat Sc d derived bands leading to a peak in the density of states and Stoner ferromagnetism. The calculated local spin density and generalized gradient approximation spin magnetizations are both enhanced with respect to experimen...
متن کاملMicroscopic conditions favoring itinerant ferromagnetism
A systematic investigation of the microscopic conditions stabilizing itinerant ferromagnetism of correlated electrons in a single-band model is presented. Quantitative results are obtained by quantum Monte Carlo simulations for a model with Hubbard interaction U and direct Heisenberg exchange interaction F within the dynamical mean-field theory. Special emphasis is placed on the investigation o...
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 کاملrole of cultural iran in promotion of multilaieralism in central asia and caucasus
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
