✦ Synopsis

The structure and magnetic arrangement in Bi 0.25 Ho 0.25 Ca 0.5 MnO 3 have been studied by powder neutron diffraction. At room temperature, the compound is in paramagnetic phase of small monoclinic distortion allowing for structural description in orthorhombic Pnma symmetry. At 10 K, the ground magnetic state was specified as CE-type antiferromagnetic.
