The crystal and magnetic structure of (Ho0.50+xCa0.50-x)(Mn1-xCrx)O3 (x = 0:00, 0.01, 0.02, 0.03) has been investigated between 5 and 300 K by means of neutron powder diffraction followed by Rietveld refinement and dc magnetic measurements. During cooling an orthorhombic to monoclinic phase transition occurs on account of the charge and orbital...

The crystal and magnetic structures of LaCrO3 and La(Cr0.90Ti0.10)O3 have been investigated between 5 and 350 K by means of neutron powder diffraction and DC magnetic measurements. Both compounds are characterized by an antiferromagnetic Gx-type ordering at low temperature. Structural features suggest the occurrence of Ti in the tetra-valent...

The crystal and magnetic structures of (Tm0.50Ca0.50)MnO3 and (Lu0.50Ca0.50)MnO3 have been investigated between 5 K and 300 K by means of high resolution neutron powder diffraction followed by Rietveld refinement and dc magnetic measurements. During cooling orbital ordering at the Mn sublattice takes place at TOO280 K in both compounds,...

The crystal and magnetic structures of the (La0.63Ca0.37)(Mn1xTMx)O3 compounds (x = 0.00, 0.03,0.08; TM = Cu2+, Ni2+) were investigated between 5K and 300K by means of dc magnetic measurements and neutron powder diffraction analysis followed by Rietveld refinement. Both substituting cations lead to a reduction of the long range ferromagnetic...

The crystal and magnetic structures of 10 and 20 nm sized (La1-xCax)MnO3 (x = 0.37, 0.50, 0.75) have been investigated between 5 and 300 K by means of Rietveld refinement of neutron powder diffraction data, coupled with transmission electron microscope observation and magnetization measurements. TEM observation reveals that nanoparticles are...
