Pressure Dependence of Ferromagnetic Curie Temperature and Colossal Magnetoresistance Effect in Pyrochlore Manganites

Negative pressure dependence of ferromagnetic Curie temperature Tc is established by the susceptibility measurements on a series of isostructural pyrochlores A2Mn2O7, (A=Tl, In, Y, Lu). At temperatures well below and above Tc the pronounced magnetothermohistory effects are revealed, indicating the p...
