Times Cited Count：10 Percentile：45.99(Materials Science, Multidisciplinary)To specify preferential occupation sites of Co substituents and to clarify charge and spin states of Co ions in (La, Co)-cosubstituted hexagonal magnetoplumbite-type (M-type) Sr ferrite, Fe and Co nuclear magnetic resonance (NMR) spectra are measured under zero and external magnetic fields using powdered and single crystalline specimens. To a considerable degree, the charge compensation between La
and Co
works in the equal (La, Co)-codoped case, where more than half of the Co ions are considered to be present in the minority spin 
sites at the center of the oxygen tetrahedra, with the 
= 3/2 state carrying a small orbital moment owing to spin-orbit interaction. The remaining small number of high-spin Co ( = 3/2, 
= 1) ions with unquenched orbital moments would be distributed to the other octahedral 
, 
, and 
sites.

Monju, the Japanese prototype of fast breeder reactor, has engaged in various activities to restore the public trust since the sodium leak accident occurred in 1995. Among the activities is the publication of a risk communication booklet "Response to the possible accident and trouble in Monju" which is compiled according to the operational progress of "Monju". This booklet is intended for promoting the public understanding toward the restart. The supplement of the booklet illustrates the outline and characteristics of "Monju", the recent troubles at not only "Monju", but also home and abroad, and the assumed troubles during the core confirmation test which is implemented when the system start-up test is commenced. These efforts for the restart are also explained.
