Magnetic Properties of Mn-Doped Amorphous SiO2 Matrix
(Acta Physica Polonica A, 2011)
Samples of Mn-doped amorphous SiO2 matrix with manganese concentration 0.7 and 3 at.% have been prepared by a sol-gel method. Transmission electron microscopy analysis has shown that the samples contain agglomerates of ...
Room-Temperature Ferromagnetism in Zn-Mn-O, X-Ray Photoemission Surface Study
(Acta Physica Polonica A, 2011)
Room temperature ferromagnetic properties of Zn-Mn-O show evident dependence on manganese concentration and preparation conditions. We systematically studied series of samples with manganese concentration ranging from 0 ...
