Effect of high temperature sintering on the structural and the magnetic properties of La1.4Ca1.6Mn2O7
Tasarkuyu, E.; Coskun, A.; Irmak, A. E.; Akturk, S.; Unlu, G.; Samancioglu, Y.; Acet, M. (Elsevier Science Sa, 2011)We investigate the effect of sintering temperature on the structural and magnetic properties of La1.4Ca1.6Mn2O7 double perovskite manganite compound prepared by the sol-gel route. Three sintering temperatures (1273, 1473 ... -
Elaboration of the structural and physical characteristics: Ni-doped ZnO bulk samples prepared by solid state reactions
Bulun, G.; Ekicibil, A.; Cetin, S. K.; Demirdis, S.; Coskun, A.; Kiymac, K. (Natl Inst Optoelectronics, 2011)Ni-doped ZnO (Zn1-xNixO, with 0.25 <= x <= 0.50) diluted magnetic semiconductors were prepared by the solid state reaction method. We have studied the structural properties of the samples by using the X-Ray Diffraction ... -
Magnetic and electrical transport properties of La0.65Ca0.30Pb0.05Mn0.90Cu0.10O3 compounds: Thermal hysteresis
Irmak, A. E.; Tasarkuyu, E.; Coskun, A.; Acet, M.; Samancioglu, Y.; Akturk, S. (Elsevier, 2015)Structural, electrical, and magnetic properties of La-0.65(Ca0.30Pb0.05)Mn0.90Cu0.10O3 compound were investigated. The compound, prepared by the sol-gel route, was pressed into pellets and one of them was sintered at 900 ... -
Magnetic properties of A- and B-site cation doped La0.65Ca0.35MnO3 manganites
Samancioglu, Y.; Coskun, A. (Elsevier Science Sa, 2010)The La0.65Ca0.35MnO3, La0.65Ca0.30Pb0.05MnO3 and La0.65Ca0.30Pb0.05Mn0.9Cu0.1O3 compounds, prepared by the sol-gel method and sintered in air at 1100 degrees C for 24 h, have been investigated by Magnetic Properties ... -
