New manifestations of a pseudogap state and electron spin scattering in the low-temperature thermal properties of near-stoichiometric iron-vanadium-aluminum alloys

Abstract

The temperature dependences of the specific heat and thermal conductivity, as well as magnetic-field induced changes in the thermal conductivity, are studied in iron-vanadium-aluminum alloys that exhibit anomalous electron properties for certain near-stoichiometric compositions. Based on previous work, we develop some ideas regarding particular features of the electron structure in these alloys (narrow pseudogap, strong spin scattering, etc.) that may be of interest both for discovering new classes of materials and for technical applications.
