Abstract

The electron transport properties of highly c-axis oriented MnBi thin films of various thicknesses have been investigated. Samples are metallic but the low temperature resistivity shows an unusual T3 dependence. Transverse Hall effect measurements show that both the ordinary and anomalous Hall coefficients decrease with decreasing temperature below 300K, but the ordinary Hall coefficient (R0) undergoes a sign reversal around 105K, where the magnetic anisotropy also changes sign. Analysis of the Hall data for various samples shows that the anomalous Hall coefficient (Rs) exhibits a strong 2 dependence, where is the longitudinal resistivity.
