Temperature dependence of the coercive field in single-domain particle systems
W. C. Nunes, W. S. D. Folly, J. P. Sinnecker +1
The magnetic properties of Cu97Co3 and Cu90Co10 granular alloys were measured over a wide temperature range (2 to 300K). The measurements show an unusual temperature dependence of…

Low temperature specific heat of the molecular cluster Fe: contribution of the local field
A. M. Gomes, M. A. Novak, W. C. Nunes +1
We present low temperature specific heat and ac-susceptibility measurements on Fe powdered sample. Below 1.3 K, superparamagnetic blocking effects as well as an excess specif…
