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 the coercive field. A generalized model is proposed and explains well

The effect of grain size, easy magnetization axis and anisotropy constant distributions in the irreversible magnetic behavior of granular alloys is considered. A simulated granular alloy is used to provide a realistic grain structure for the Monte Ca

We present low temperature specific heat and ac-susceptibility measurements on Fe$_{8}$ powdered sample. Below 1.3 K, superparamagnetic blocking effects as well as an excess specific heat contribution are evident. The latter is attributed to a splitt

Charcoal rot is an economically important fungal disease of economically important crops. Several species of the Macrophomina genus, such as M. pseudophaseolina and M. euphorbiicola, may act as the causal agents of charcoal rot. The current study eva
