Abstract:

The effect of hydrostatic pressure up to 1 GPa on the electrical resistivity and on the ferromagnetic transition temperature T0 is systematically investigated for the electron-doped manganite Ca 1 -xYxMnO3 for low electron density (x ≤ 0.2). We find that T0 is nearly constant for pressures roughly below 0.5 GPa and shows a linear increase for higher pressures, with a slope varying with the x content. Our results are discussed considering the enhancement of the electronic bandwidth with pressure related to double exchange and polaronic contributions. The unusual pressure dependence of T0 obtained can also be related to a competition scenario between double exchange mechanism and antiferromagnetic superexchange interactions proposed for electron-doped manganites. © 2001 Elsevier Science B.V.
