Article Synopsis
  • The study examines the magnetic, electrical, and thermal properties of Ni alloys with variations in V, Cr, and Nb, highlighting weak itinerant ferromagnetism in certain compositions and a suppression of ferromagnetic ordering between concentrations of 10 and 12.
  • An unusual low-temperature variation in specific heat suggests a non-Fermi-liquid behavior near critical concentration, with increased correlations indicated by a higher Kadowaki-Woods ratio.
  • The data supports theories of quantum phase transitions and suggests that these Ni-rich alloys could be potential candidates for observing Griffith phases due to the effects of spin fluctuations.

Agriculture is one of the prime activities of the hill people residing in the northwestern Indian Himalaya. However, poor soil fertility in these areas is a big hurdle to sustainable farming. The effects of washout of topsoil and its nutrients, year after year, due to the abundance of snowfall, avalanches, landslides and erosion further add to the woes of the farmers.

Salix fragilis is the most common willow species grown extensively under the indigenous agroforestry system in the cold desert of Lahaul valley located in the northwestern Himalayas, India. Presently, this tree is under severe pest attack, and other infections have made its survival in the area questionable. This deciduous multipurpose tree species provides vegetation cover to the barren landscape of Lahaul and is a significant contributor of fuel and fodder to the region.
