  • Title: Resistivity Minimum in Highly Frustrated Itinerant Magnets.
    Author: Wang Z, Barros K, Chern GW, Maslov DL, Batista CD.
    Journal: Phys Rev Lett; 2016 Nov 11; 117(20):206601. PubMed ID: 27886479.
    Abstract:
    We study the transport properties of frustrated itinerant magnets comprising localized classical moments, which interact via exchange with the conduction electrons. Strong frustration stabilizes a liquidlike spin state, which extends down to temperatures well below the effective Ruderman-Kittel-Kasuya-Yosida interaction scale. The crossover into this state is characterized by spin structure factor enhancement at wave vectors smaller than twice the Fermi wave vector magnitude. The corresponding enhancement of electron scattering generates a resistivity upturn at decreasing temperatures.
