説明

Magnetic properties of (Mn1−xMox)3B4 and (Mn1−xWx)3B4, where x ranges from 0.01 to 0.667, were studied by the measurements of magnetization, unit cell dimension, rotational hysteresis and internal field of Mn55. Unit cell dimensions for both Mo- and W-modified Mn3B4 were found to increase continuously with increasing x indicating that solid solutions are formed in this composition range. Magnetization measurements showed that Mo or W addition results in ferromagnetic part in antiferromagnetic host of Mn3B4. The expected value for the magnetic moment of a Mn atom on 4(g)-site is about 1.5μB for all the Mn3B4-type compounds studied.
