Third order perturbed modified Heisenberg Hamiltonian of fcc structured ferromagnetic films with seventy spin layers
P. Samarasekara, N. U. S. Yapa, C. A. N. Fernando
Magnetic properties of fcc structured ferromagnetic films with the number of spin layers up to seventy was described using third order perturbed Heisenberg Hamiltonian. The variati…
Optical properties of spin coated Cu doped ZnO nanocomposite films
P. Samarasekara, Udumbara Wijesinghe
Spin coating technique was used to synthesize pure ZnO and Cu doped ZnO films on amorphous and conducting glass substrates. The doped amount of Cu in ZnO was varied up to 5% in ato…
Third order perturbed Heisenberg Hamiltonian of sc ferromagnetic films with fifty spin layers
N. U. S. Yapa, P. Samarasekara
Magnetic energy of simple cubic structured ferromagnetic films with 10 to 50 spin layers was determined using third order perturbed Heisenberg Hamiltonian. By plotting 3-D plot of…
Photocurrent enhancement of spin coated CdS thin films by adding Cu
P. Samarasekara, B. M. M. B. Basnayaka, Sunil Dehipawala
Cu added CdS films were synthesized using spin coating technique at different spin speeds for different time durations. Films were subsequently annealed at different temperatures f…
Magnetic Dipole Interaction and Total Magnetic Energy of Lithium Ferrire Thin Films
P. Samarasekara, C. K. D. Sirimanna
The total magnetic energy of Lithium ferrite thin films was determined using the classical Heisenberg Hamiltonian. The short range magnetic dipole interactions between spins within…
Impedance and electrical properties of Cu doped ZnO thin films
P. Samarasekara, Udumbara Wijesinghe, E. N. Jayaweera
Cu doped transparent ZnO thin films were spin coated on conductive glass substrates. The samples were subsequently annealed in air for 1 hour at 500 0C in order to form the phase o…
