{ "DOI": "10.1103/PhysRevB.78.144408", "abstract": "La0.5Pr0.5Mn2Si2 exhibits an antiferromagnetic-ferromagnetic transition caused by the crossover of the critical distance between Mn atoms on changing temperature. Applying a magnetic field in the antiferromagnetic state can cause a field-induced transformation to the ferromagnetic state at a critical field, which increases with decreasing temperature. We study here with magnetization and strain measurements the magnetic-field-induced strain associated with the field-induced transformation and magnetocaloric effects close to the transition temperature. We also examine the temperature dependence of the critical field and find from magnetization and ferromagnetic resonance measurements that short-range ferromagnetic correlation among the rare earth and Mn-sublattices occur at low temperatures. At low temperatures, this causes a decrease in the critical field for the crossover from antiferromagnetic to ferromagnetic coupling with decreasing temperature.", "author": [ { "family": "Emre", "given": " B." }, { "family": "Aksoy", "given": " S." }, { "family": "Posth", "given": " O." }, { "family": "Acet", "given": " M." }, { "family": "Duman", "given": " E." }, { "family": "Lindner", "given": " J." }, { "family": "Elerman", "given": " Y." } ], "container_title": "PHYSICAL REVIEW B", "id": "39927", "issue": "14", "issued": { "date-parts": [ [ 2008, 1, 1 ] ] }, "title": "Antiferromagnetic-ferromagnetic crossover in La0.5Pr0.5Mn2Si2 and its consequences on magnetoelastic and magnetocaloric properties", "type": "article-journal", "volume": "78" }
