Cross-relaxation and phonon bottleneck effects on magnetization dynamics in LiYF4:Ho3+
S. Bertaina, B. Barbara, R. Giraud +5
Frequency and dc magnetic field dependences of dynamic susceptibility in diluted paramagnets LiYF:Ho have been measured at liquid helium temperatures in the ac and dc ma…
Muon spin rotation studies of spin dynamics at avoided level crossings in LiY0.998Ho0.002F4
M. J. Graf, J. Lago, A. Lascialfari +6
We have studied the Ho3+ spin dynamics for LiY0.998Ho0.002F4 through the positive muon (mu+) transverse field depolarization rate lambda_TF as a function of temperature and magneti…
The quantum dynamics of atomic magnets, co-tunneling and dipolar-biased tunneling
R. Giraud, A. M. Tkachuk, B. Barbara
Multi-spins tunneling cross-relaxations in an ensemble of weakly-coupled Ho ions, mediated by weak anisotropic dipolar interactions, can be evidenced by ac-susceptibility me…
Tunneling of magnetization versus spin-phonon and spin-spin transitions in LiY_0.998Ho_0.002F_4
R. Giraud, W. Wernsdorfer, A. M. Tkachuk +2
Strong hyperfine coupling in a 0.2% Holmium doped LiYF_4 single crystal induces staircaselike hysteresis loops of the magnetization at very low temperatures. The field sweep rate d…
