Size and interface effects in the phase transitions of antiferromagnetic superlattices
(Elsevier B.V., 1992-04)
A self-consistent mean field theory is used to study composition effects on the phase transitions of FeF2/CoF2 and FeF2/MnF2 superlattices under weak applied fields. The temperature dependence of the magnetization is shown ...
Reproductive Patterns and Birth Seasonality in a South-American Breeding Colony of Common Marmosets, Callithrix jacchus
(Primates, 1999-04)
We analyzed data on captive-born and wild-caught females housed under natural conditions in a colony located in northeastern Brazil. No differences in reproductive performance were found
between captive-born and wild-caught ...
