ABSTRACT
Single-crystalline SrMn3O6-δ nanoribbons (width of 30–500 nm and lengths of up to several hundred micrometers) are synthesized by a molten-salt method. In contrast with the antiferromagnetism in bulk SrMn3O6-δ, magnetization measurements show weak ferromagnetism in these nanoribbons at low temperature. In particular, a notable exchange-bias effect, which strongly depends on the cooling field, is observed in applied magnetic field H≤5 kOe. These results suggest that the exchange bias in the SrMn3O6-δ nanoribbons can be effectively tuned by the cooling field, which is of very special interests for applications.

    The temperature dependences M(T) and field dependences M(H) of the magnetization have been measured in single-crystal TbBaCo4O7 for two magnetic-field directions: H∥c and H⊥c. In the case of H∥c, a magnetic field-induced irreversible transition is detected at low temperatures,...

    The lateral unit cell parameter in nanodimensional La0.67Ca0.33MnO3 (LCMO) films grown on (001)-oriented LaAlO3 substrates is significantly (approximately 4%) smaller than the value measured along the normal to the substrate plane. At T < 140 K, the temperature dependence of the resistivity ρ...
