Non-Fermi Liquid Behavior in a Weak Itinerant Ferromagnet MnSi
MnSi is a weak itinerant helimagnet with a relatively low order magnetic moment. Temperature dependance of resistivity shows that it enters non-Fermi liquid state above a critical pressure pc which remains to be understood. The observed partial magnetic order above pc indicates novel metallic state. Here, Fermi liquid and non-Fermi liquid theories are discussed with the main focus on the temper...
متن کاملItinerant Magnetism in Metallic CuFe2Ge2
Theoretical calculations are performed to understand the electronic structure and magnetic properties of CuFe2Ge2. The band structure reveals large electron density N(EF) at the Fermi level suggesting a strong itinerant character of magnetism. The Fermi surface is dominated by two dimensional sheet like structures, with potentially strong nesting between them. The magnetic ground state appears ...
متن کاملac susceptibility studies of the weak itinerant ferromagnet SrRuO3 under high pressure to 34 GPa
The dependence of the Curie temperature TCurie on nearly hydrostatic pressure has been determined to 17.2 GPa for the weak itinerant ferromagnet SrRuO3 in both polycrystalline and single-crystalline forms. TCurie is found to decrease under pressure from 162 to 42.7 K at 17.2 GPa in nearly linear fashion at the rate dTCurie /dP −6.8 K/GPa. No superconductivity was found above 4 K in the pressure...
متن کاملStudies on the weak itinerant ferromagnet SrRuO 3 under high pressure to 34 GPa
The dependence of the Curie temperature T Curie on nearly hydrostatic pressure has been determined to 17 GPa for the weak itinerant ferromagnetic SrRuO 3 in both polycrystalline and single-crystalline form. T Curie is found to decrease under pressure from 162 K to 42.7 K at 17.2 GPa in nearly linear fashion at the rate dT Curie /dP ≃ −6.8 K/GPa. No superconductivity was found above 4 K in the p...
متن کاملItinerant magnetism in doped semiconducting β-FeSi2 and CrSi2
Novel or unusual magnetism is a subject of considerable interest, particularly in metals and degenerate semiconductors. In such materials the interplay of magnetism, transport and other Fermi liquid properties can lead to fascinating physical behavior. One example is in magnetic semiconductors, where spin polarized currents may be controlled and used. We report density functional calculations p...
