LiV 2 O 4 Spinel as a Heavy-Mass Fermi Liquid: Anomalous Transport and Role of Geometrical Frustration

摘要: Transport and specific heat measurements on hydrothermally grown single crystals reveal the formation of a heavy-mass Fermi liquid in ${\mathrm{LiV}}_{2}{\mathrm{O}}_{4}$ spinel, below coherence temperature ${T}^{*}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}20--30\mathrm{K}$. A few observations which illustrate uniqueness this spinel are discussed connection with origin heavy mass, such as anomalous absence resistivity saturation above ${T}^{*}$ close proximity to spin glass phase where influence magnetic frustration is evident.
