Description

We present a comparative investigation of the Bi manganites with commensurate composition x=14: Bi0.75Sr0.25MnO3 and Bi0.75Ca0.25MnO3. μSR and diffraction data confirm different structural, magnetic and electronic transitions in the two compounds. The robust charge-order phase detected with Sr do not occur in Bi0.75Ca0.25MnO3, which present inhomogeneous magnetism and short-range charge order. In both compounds the application of magnetic fields produces a continuous progressive canting of the moments, visible even for relatively small fields (μ0H-bar 1T)
