Magnetic properties and crystallization of amorphous Fe74Co10B16 have been investigated by Mössbauer and DSC measurements. Probability distribution of hyperfine field P(H) shows a single peak which shifts to lower fields with increase in temperature. Crystallization has been found to give rise to α-(Fe-Co), Fe2B and (Fe-Co)2B phases. 相似文献

The Knight shift at positive muons implanted in pure palladium has been measured as a function of temperature from 19.8 to 883 K. The Knight shift variation is strictly proportional to the Pd magnetic susceptibility with ΔKμ/Δx=-(0.43±0.02) mole/emu=-(2.39±0.11)kG/μB. A temperature independent term Kμ(x=0)=+45±10 ppm is found. The results are discussed in terms of the electronic structure of H in Pd. 相似文献

μSR‐measurements in ZF and LF on Nd1.4Ce0.2Sr0.4CuO4-\delta show a sharp increase of the depolarisation rate (\lambda) below \approx\,2K. This increase can be explained by the transition
from uncorrelated to correlated spin fluctuations, which is in agreement with results obtained by neutron scattering.

The spin relaxation of Mu was measured in mixtures of CO and Ar at pressures up to 270 atm and at various magnetic fields.
The relaxation rate increased with magnetic field in the way expected for electron spin‐exchange processes, though the effect
declined at high pressures. We describe the results in terms of spin relaxation of Mu‐formyl radicals, MuCO, which break up
to give depolarized Mu at low pressures, but are increasingly stabilized at higher pressures.

The dependence of the hyperfine field at an interstitial positive muon in ferromagnetic field has been measured at room temperature yielding a Knight Shift constant K = 0.0025 (3). This Knight shift is interpreted in terms of the Pauli spin paramagnetism of s-p band electrons. 相似文献

A systematic μ+SR study of the magnetic heavy-electron systems U2Zn17 and UCu5 in the paramagnetic and in the magnetically ordered state is presented. In both systems the antiferromagnetic nature of the
low-temperature phase could be at least partially confirmed, but the muon reveals significant differences with regard to the
phase transition itself. UCu5 behaves like a model-antiferromagnet showing a drastic increase of the relaxation rate both below and above TN, two spontaneous frequencies in the ordered phase, and a Knight shift above TN which scales with the bulk susceptibility. In contrast U2Zn17 shows a loss of μ+ asymmetry by 20% below TN, which is independent of the external field but can be quenched in sufficiently strong longitudinal fields. No scaling of
the Knight shift and the susceptibility was observed and no critical increase of the relaxation rate λ. Most astonishing is
the strong and nonlinear field dependence of λ above and below TN in both compounds. The absence of longitudinal relaxation demonstrates the static origin of λ. 相似文献
