Alloy thin films of ternary system Co – Ni – Fe and binary systems Co – Fe , Co – Ni and Ni – Fe consisting of ~50 nm grains have been deposited by a simple and industrially viable technique of electrodeposition in galvanostatic mode on ITO-coated glass. Bath composition and current density have been varied to prepare films of different compositions and thus, in turn, obtain suitable composition for better magnetic properties. Further, an attempt has been made to deposit films in the presence of Mg 2+ in the bath and to study its linkage with the magnetic properties, i.e., saturation magnetic flux density, BS, and coercivity, HC. Our results clearly demonstrate that addition of Mg 2+ ions in the bath helps in increasing the BS considerably.

SYNOPSISThis paper presents an investigation on an open cycle absorption solar cooling system with solution storage for continuous operation. A simple heat and mass transfer analysis for predicting the water mass evaporation rate under steady state and transient conditions have been presented. Basic mass, material, and heat balance equations along with fluid properties state equation have been used and parametric results for the mass of the anhydrous salt andlor water mass content in the solution required for system operation have been predicted as a function of climatic parameters and initial solution condition. It is found that an open cycle absorption cooling system with solution storage option is feasible for continuous air-conditioning.
