Element-resolved ultrafast demagnetization rates in ferrimagnetic CoDy
T. Ferte, N. Bergeard, L. Le Guyader +7
Femtosecond laser induced ultrafast magnetization dynamics have been studied in multisublattice CoxDy1-x alloys. By performing element and time-resolved X-ray spectroscopy, we dist…
Identification of spin wave resonances and crystal field transitions in simple chromites RCrO3 (R=Pr, Sm, Er) at ultralow temperatures in the THz spectral region
Néstor E. Massa, Karsten Holldack, Rodolphe Sopracase +4
We report on THz absorption spectroscopy combined with high magnetic fields of polycrystalline RCrO3 (R= Pr, Sm, Er) aiming understanding spin wave resonances at their low temperat…
Analysis of Granular Packing Structure by Scattering of THz Radiation
Philip Born, Karsten Holldack
Scattering methods are widespread used to characterize the structure and constituents of matter on small length scales. This motivates this introductory text on identifying prospec…
Ultrafast and Energy-Efficient Quenching of Spin Order: Antiferromagnetism Beats Ferromagnetism
Nele Thielemann-Kühn, Daniel Schick, Niko Pontius +6
By comparing femtosecond laser pulse induced ferro- and antiferromagnetic dynamics in one and the same material - metallic dysprosium - we show both to behave fundamentally differe…
