摘要：

The CMR manganites Ln(1 - x)A(x)MnO(3) with the perovskite structure form a very important family of magnetic oxides, studied for their fascinating colossal magnetotransport properties. In this review, we discuss two phenomena, charge ordering and phase separation, which are crucial for the appearance of CMR in these oxides. We propose a new route to CMR, based on the Mn-site doping of these materials by other cations, such as Cr, Co, Ni and Ru.
