摘要：

X-ray diffraction, neutron diffraction, resistivity, and magnetization versus composition and temperature have been used to characterize a magnetically dilute mixed crystal series of La0.8Sr0.2Cu(x)Mn(1-x)O3 (O less-than-or-equal-to x less-than-or-equal-to 0.4). The Raman spectra of these compounds are presented for the first time; they show various phonon bands and an anomalous broad band at 650 cm-1 which we tentatively connect with magnetic or electronic excitations.
