The Hall Effect in MnSe Films
B Y M. A. ANGADI and V. THANIGAIMANIThe Hall effect is rcported for MnSe films of different compositions and thickness in the range 30 to 150 nm. Both Ro and R, are dependent on thickness, composition, and substrate temperature. R, and R, cxhibit both positive and negative values for different thickness ranges studied. The extraordinary Hall coefficient is proportional to the square of the total film resistivity for higher thicknesses ( > 100 nm).') St. Augustine, Trinidad & Tobago, West Indies.
