Energy Level Lifetimes in the Single-Molecule Magnet Fe_8 : Experiments and Simulations
S. Bahr, K. Petukhov, V. Mosser +1
We present pump-probe measurements on the single-molecule magnet Fe_8 with microwave pulses having a length of several nanoseconds. The microwave radiation in the experiments is lo…
Pump-Probe Experiments on the Single-Molecule Magnet Fe8 : Measurement of Excited Level Lifetimes
S. Bahr, K. Petukhov, V. Mosser +1
We present magnetization measurements on the single molecule magnet Fe8 in the presence of pulsed microwave radiation. A pump-probe technique is used with two microwave pulses with…
Absence of Conventional Spin-Glass Transition in the Ising Dipolar System LiHo_xY_{1-x}F_4
P. E. Jönsson, R. Mathieu, W. Wernsdorfer +2
The magnetic properties of single crystals of LiHo_xY_{1-x}F_4 with x=16.5% and x=4.5% were recorded down to 35 mK using a micro-SQUID magnetometer. While this system is considered…
Magnetization dynamics in the single-molecule magnet Fe8 under pulsed microwave irradiation
K. Petukhov, S. Bahr, W. Wernsdorfer +2
We present measurements on the single molecule magnet Fe8 in the presence of pulsed microwave radiation at 118 GHz. The spin dynamics is studied via time resolved magnetization exp…
