19F nuclear spin relaxation and spin diffusion effects in the single-ion magnet LiYF 4:Ho 3+

Malkin B.; Vanyunin M.; Graf M.; Lago J.; Borsa F.; Lascialfari A.; Tkachuk A.; Barbara B. (2008)

Temperature and magnetic field dependences of the 19F nuclear spin-lattice relaxation in a single crystal of LiYF 4 doped with holmium are described by an approach based on a detailed consideration of the magnetic dipole-dipole ...
Evolution of spin relaxation processes in LiY 1-xHo xF 4 studied via ac-susceptibility and muon spin relaxation

Johnson R.; Malkin B.; Lord J.; Giblin S.; Amato A.; Baines C.; Lascialfari A.; Barbara B.; Graf M. (2012)

We present measurements of magnetic field and frequency dependence of the low-temperature (T = 1.8 K) ac-susceptibility and temperature and field dependence of the longitudinal field positive muon spin relaxation (μSR) for ...
Suppression of μ+ depolarization by fast magnetic fluctuations at avoided level crossings for H o3+ ions in CaW O4

Kenney E.; Amato A.; Giblin S.; Malkin B.; Graf M. (2018)

© 2018 American Physical Society. We use transverse field muon spin rotation to probe the low field dynamics of Ho3+ ions imbedded in a single crystal host matrix of CaWO4. The Ho3+ ions at sites with the full tetragonal ...
μsR study of spin dynamics in LiY1-xHoxF 4

Johnson R.; Chen K.; Giblin S.; Lord J.; Amato A.; Baines C.; Barbara B.; Malkin B.; Graf M. (2011)

We present zero-field positive muon spin relaxation (μSR) measurements for LiY1-xHoxF4 samples with x = 0.0017, 0.0085, 0.0406, and 0.0855. We characterize the dynamics associated with the formation of the (F-μ-F)- complex ...
