Abstract

We conducted magnetic and transport measurements on the "bulrush-like" double perovskite Ba₂Fe_1.1Mo_0.9O₆ generated in a wet chemistry method. The sample contains Ba₂Fe_1.1Mo_0.9O₆ crystallites with average width of 120 nm and length larger than 2 μm. Utilizing the bulrush-like sample of high aspect ratio, we have fabricated a material of electric anisotropy with large tunneling magnetoresistance, Δρ/ρ₀, -34.5--26.6% at a low magnetic field of 10 kOe over a wide temperature range from 80 to 300 K.
