Ferrimagnetic order in the mixed rare-earth iron garnet {Y 1-x Gd x } 3 Fe 5 O 12 system has been reinvestigated to cover the temperature range 5.0 to 700 K. The magnetization versus temperature exhibits a systematic variation with changing concentration x. The ferric-ion exchange coupling is strong enough to determine the Curie temperature ≈ 559 K for all the values x. The compensation temperature at which the magnetization crosses zero (shows the minimum) demonstrates the applicability of the three-sublattice model.
New perennial canker diseases of Abies veitchii and Acer crataegifolium are described. Pathogenicity of the causal fungus was confirmed on stems of young Abies and Acer trees using two monoascospore isolates from the perithecia from the two tree species. The causal fungus, producing Nectria-state-teleomorph and Cylindrocarponanamorph, was identified as Nectria castaneicola. It was then transferred to the genus Neonectria, as N. castaneicola (W. Yamam. et Oyasu) Tak. Kobay. et Hirooka, comb. nov. followed by the recent concept of Nectriaceae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
