WebFeb 11, 2013 · Incommensurate density waves emerge in a wide variety of correlated electron systems. They are a common aspect in cuprate superconductors ( 1, 2 ), itinerant transition-metal magnets ( 3, 4 ), and rare-earth compounds ( 5 – 7 ), as well as low-dimensional charge-ordered materials ( 8, 9) and perovskite manganites ( 10, 11 ). Spin-density wave (SDW) and charge-density wave (CDW) are names for two similar low-energy ordered states of solids. Both these states occur at low temperature in anisotropic, low-dimensional materials or in metals that have high densities of states at the Fermi level . Other low-temperature ground states that occur in such materials are superconductivity, ferromagnetism and antiferr… flashback o boticario https://ashishbommina.com
