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 کاملMagnetoresistance at artificial interfaces in the itinerant SrRuO3 ferromagnet
The magnetoresistance across interfaces in the itinerant ferromagnetic oxide SrRuO3 have been studied. To define appropriately the interfaces, epitaxial thin films have been grown on bicrystalline and laser-patterned SrTiO3 substrates. Comparison is made with results obtained on similar experiments using the doubleexchange ferromagnetic oxide La2/3Sr1/3MnO3. It is found that in SrRuO3, interfac...
متن کاملMagnetic phase transition in the itinerant helimagnet MnSi: Thermodynamic and transport properties
A careful study of thermodynamic and transport properties of a high-quality single crystal of MnSi at ambient pressure suggests that its transition to a helical magnetic state near 29 K is weakly first order. The heat capacity, temperature derivative of resistivity, thermal expansion, and magnetic susceptibility exhibit a specific structure around the phase transition point, interpreted as a co...

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...
