摘要：

The depolarization rate for spin polarized μ+ particles implanted into high purity polycrystalline nickel and iron samples were studied as a function of temperature in zero external field. In nickel a rapid decrease of the depolarization rate above 300 K was found. Assuming an Arrhenius behaviour, an activation energy of Ea=173 meV was determined. In iron it was not possible to fit the data with a simple Arrhenius law. At least two different slopes can be observed in an Arrhenius plot with Ea=(124±35) meV and Ea=(19±2) meV, respectively. © 1979 North-Holland Publishing Company.
