Structural and Magnetic Dynamics in the Magnetic Shape Memory Alloy NiMnGa
S. O. Mariager, C. Dornes, J. A. Johnson +11
Magnetic shape memory Heusler alloys are multiferroics stabilized by the correlations between electronic, magnetic and structural order. To study these correlations we use time res…
Direct observation of non-fully-symmetric coherent optical phonons by femtosecond x-ray diffraction
S. L. Johnson, P. Beaud, E. Möhr-Vorobeva +3
We directly measure by femtosecond time-resolved x-ray diffraction the E symmetry coherent phonon excited in bismuth by strong optical excitation. The magnitude of the E mo…
Coherent phonon dynamics at the martensitic phase transition of Ni_2MnGa
S. O. Mariager, A. Caviezel, P. Beaud +2
We use time-resolved optical reflectivity to study the laser stimulated dynamics in the magnetic shape memory alloy Ni_2MnGa. We observe two coherent optical phonons, at 1.2 THz in…
Structural and magnetic dynamics of a laser induced phase transition in FeRh
S. O. Mariager, F. Pressacco, G. Ingold +11
We use time-resolved x-ray diffraction and magnetic optical Kerr effect to study the laser induced antiferromagnetic to ferromagnetic phase transition in FeRh. The structural respo…
