Relationship between Demagnetization Factor and Energy of Thick Ferromagnetic Films
Abstract: The variation of energy of ferromagnetic thick films of 10000 layers with demagnetization factor will be described in this report using second order perturbed Heisenberg Hamiltonian. Under the influence of demagnetization factor given by =6.6, the sc(001) film with 10000 layers can be easily oriented in 0.6 radians direction for the values of energy parameters used in this report. Easy direction of thick fcc(001) film with 10000 layers was determined …

Ultrasonic Study of Molecular Interactions in Organic Liquids at Various Temperatures and Concentrations
Abstract: The ultrasonic velocity was measured for water and glacial acetic acid in their pure state and in their binary mixtures. The ultrasonic velocity was measured also for the solution of salicylic acid in glacial acetic acid. Relative density and relative viscosity were also measured at various temperatures and concentrations. The parameters like adiabatic compressibility, acoustic impedance, relaxation time and attenuation were determined. This study is helpful for the understanding of …

The Problem Involving the Quantification of Quantum Discord
Abstract: For the last few years, people are concentrating on studying different aspects of non-locality of quantum mechanics. Many correlation measures have been introduced and well-studied. Quantum discord is one of such correlation measures that creates new challenges among the physicists and mathematicians. New quantification of quantum discord is one of the fascinating areas. In this paper, we study for the investigation of the difficulties in finding the analytic expression of …
