Abstract
The muon spin relaxation rateΛ (T) in an orientated polycrystalline sample of erbium constructed of large monocrystals has been measured for temperatures 20 <T<300 K. It has been shown that theΛ (T) for erbium is bounded from above asT → TN, whereT N=84.4 K is the Néel temperature. This fact may be explained by assuming that atT=TN erbium undergoes a weak phase-transition of the first order.
