Magnetic ordering temperature, hyperfine field distribution and electrical resistivity of amorphous (FexMn1−x)75P16B6Al3

Abstract
Mössbauer studies of amorphous (FexMn1−x)75P16B6Al3 show a rapid drop in the magnetic ordering temperature and the development of a second, low‐field peak in the hyperfine field distribution P(H) as x is decreased from unity. The magnetic ordering does not affect the electrical resistivity, but the changes in P(H) are correlated with the appearance of a broad, high‐temperature resistance minimum. A second, anomalous resistance minimum, different from the first, appears at a low temperature which is nearly independent of x.
