Description
Magnetization measurements and neutron powder diffraction analyses followed by Rietveld refinement have been carried out in order to investigate the magnetic structures of LaYbO3 and LaHoO3. Both compounds exhibit a negative thermal expansion along the a and b axes. In LaYbO3 Yb3+ spins order at 2.4 K according to a FyGz-type structure, belonging to the Pn′ma′ magnetic space group. Conversely, LaHoO3 is paramagnetic down to 1.5 K. (paper)
