2008 (English)In: Journal of Alloys and Compounds, ISSN 0925-8388, E-ISSN 1873-4669, Vol. 457, no 1-2, 532-540 p.Article in journal (Refereed) Published
The nuclear structure and magnetic properties of perovskite-type samples of compositions LaCr1-xMnyO3 (y=0, 0.1, 0.2, 0.3) have been studied using neutron powder diffraction technique and magnetization measurements. All samples have orthorhombic structure with space group Pnma (No. 62) in the temperature range 1.5-400 K. The pure lanthanum chromate LaCrO3 is a G-type antiferromagnet with a Neel temperature of 290 K. The Mn substituted samples also order antiferromagnetically at about 290 K, with canted magnetic moments yielding a ferromagnetic component.
