(1-x)BaFe12O19/ xCoFe(2)O(4) hard/soft magnetic nanocomposites: Synthesis, physical characterization, and antibacterial activities study
Davarpanah, Abdol Mahmood; Rahdar, Abbas; Dastnae, M. Azizi; Zeybek, Orhan; Beyzaei, Hamid (Elsevier Science BV, 2019)In the current study, nanocomposites of (1-x)BaFe12O19/xCoFe(2)O(4) (x = 0.3, 0.5, and 0.7) were prepared via sal-gel method. Their structural and magnetic properties were chracterized using X-ray diffractometer (XRD), ... -
Electronic surface states of Cu(110) surface
Zeybek, Orhan; Davarpanah, Abdol Mahmood; Barrett, Steve (Elsevier Science Bv, 2006)Surface states are a unique and important class of quantum states that shave an important effect on the electronic properties of Cu(110) surface. The Cu(110) surface has been studied using ultraviolet photoemission ... -
Fractal size, occupied fraction study with annealing of heterostructure based alxga1-xn
Zeybek, Orhan; Ayaz, Ahmet; Öztürk, Mustafa Kemal; Davarpanah, Abdol Mahmood; Barrett, Steve D.; Bayırlı, Mehmet; Özçelik, Süleyman (Springer, 2018)In this study, numerical analysis of temperature variation for surface structure in AlxGa1-xN thin film grown by metal organic chemical vapour deposition has been performed. Numerical studies were carried out over morphologic ... -
Inverse photoemission spectroscopy of the unoccupied electronic structure of Na/Cu(110)
Zeybek, Orhan; Davarpanah, Abdol Mahmood; Barrett, Steve D. (Pergamon-Elsevier Science Ltd, 2006)The unoccupied electronic states of Na thin films on a Cu(110) substrate have been measured by inverse photoemission spectroscopy (WES). The WES spectrum provides the intensity of the unoccupied states, which decreases ... -
Structural, magnetic, and in vitro inhibitory characteristics of Ce-substituted MnFe2O4 nanoparticles
Mohafez, Fatemeh Sorayyah; Davarpanah, Abdol Mahmood; Rahdar, Abbas; Beyzaei, Hamid; Zeybek, Orhan; Barrett, S. D. (Springer Heidelberg, 2021)MnCexFe2-xO4 (x = 0.0, 0.6, 1.4) nanoparticles were successfully synthesized via sol-gel method. Their structural and magnetic properties were studied using X-ray diffraction, scanning electron microscopy, energy-dispersive ... -
Surface resonance transition of roughened Cu(110)
Zeybek, Orhan; Davarpanah, Abdol Mahmood; Barrett, Stephen D; Martin, D. S (Elsevier Science Bv, 2007)The temperature dependence of the reflection anisotropy spectroscopy (RAS) of a Cu(1 1 0) surface has been studied over the temperature range 700-1000 K. Because of the roughening transition at 900 K, the bimodal feature ...
