摘要：
Magnetic and transport properties of polycrystalline CaMn1-xRuxO3 (x = 0-0.4) perovskites were investigated under pressures up to 12 kbar. It was found that an applied pressure suppresses ferromagnetism and increases resistivity. The results are discussed in the context of phase separation and valence effects. (c) 2004 Elsevier B.V.
