Experimental features of the antiferromagnetism in Ba2GdCu3O/sub 7-//sub y/
- 1. Institute of Physics, Chinese Academy of Sciences, Beijing, China
Description
Structure, resistivity, Meissner effect, magnetization and specific-heat measurements were conducted on Ba2GdCu3O/sub 7-//sub y/ with different oxygen contents. The results indicate that the local symmetry breaking due to twinning or disorder of oxygen vacancies may give rise to a frustration of the collinear spin structure. The critical behavior of the specific heat is logarithmic but with different amplitudes above and below the transition temperature, implying that the magnetic transition is driven by quasi-three-dimensional magnetic interactions
