The electronic behavior of Ni nanowires in an oriented mesoporous silica thin film was reported. The hybrid film was prepared using a facile method of airflow-induced mesopore orientation from silica sol solution containing Ni2+ cation, followed by H2 reduction. Because of the confinement effect, the Ni nanowires were aligned in the oriented mesochannels, which resulted in anisotropic electronic responses. Such a property would be of great importance in the design of nanodevices for advanced photoelectric applications.

    We have studied the magnetic anisotropy of nanometric CoFe2O4 (CFO) thin films grown on (100)SrTiO3 (STO) substrates. It has been found that epitaxial substrate-induced compressive strain makes the normal-to-film axis harder than the in-plane directions. In agreement with some previous reports,...
