Antiferromagnetic spin canting and Magnetoelectric Multipoles in h-YMnO
M. Ramakrishnan, Y. Joly, Q. N. Meier +7
Hexagonal YMnO is a prototype antiferromagnet which exhibits multiferroic behavior with the ferroelectric and magnetic transitions occurring at different temperatures. We obs…
Exchange-striction driven ultrafast nonthermal lattice dynamics in NiO
Y. W. Windsor, D. Zahn, R. Kamrla +7
We use femtosecond electron diffraction to study ultrafast lattice dynamics in the highly correlated antiferromagnetic (AF) semiconductor NiO. Using the scattering vector (Q) depen…
Multiple magnetic ordering phenomena in multiferroic o-HoMnO3
Y. W. Windsor, M. Ramakrishnan, L. Rettig +4
Orthorhombic HoMnO3 is a multiferroic in which Mn antiferromagnetic order induces ferroelectricity. A second transition occurs within the multiferroic phase, in which a strong enha…
Deterministic control of an antiferromagnetic spin arrangement using ultrafast optical excitation
Y. W. Windsor, A. Ernst, K. Kummer +8
A central prospect of antiferromagnetic spintronics is to exploit magnetic properties that are unavailable with ferromagnets. However, this poses the challenge of accessing such pr…
Coupling between a charge density wave and magnetism in an Heusler material
G. Lantz, M. J. Neugebauer, M. Kubli +10
The Prototypical magnetic memory shape alloy NiMnGa undergoes various phase transitions as a function of temperature, pressure, and doping. In the low-temperature phases below…
The Spin-Reorientation Transition in TmFeO3
U. Staub, L. Rettig, E. M. Bothschafter +10
X-ray magnetic circular and linear dichroism (XMCD and XMLD) have been used to investigate the Fe magnetic response during the spin reorientation transition (SRT) in TmFeO3. These…
Crystal Symmetry Lowering in Chiral Multiferroic BaTaFeSiO observed by X-Ray Magnetic Scattering
M. Ramakrishnan, Y. Joly, Y. W. Windsor +8
Chiral multiferroic langasites have attracted attention due to their doubly-chiral magnetic ground state within an enantiomorphic crystal. We report on a detailed resonant soft X-r…
Magnetic properties of strained multiferroic CoCr2O4: a soft X-ray study
Y. W. Windsor, C. Piamonteze, M. Ramakrishnan +8
Using resonant soft X-ray techniques we follow the magnetic behavior of a strained epitaxial film of CoCr2O4, a type-II multiferroic. The film is [110]-oriented, such that both the…
Ultrafast Laser-Induced Melting of Long-Range Magnetic Order in Multiferroic TbMnO3
Jeremy A. Johnson, T. Kubacka, M. C. Hoffmann +25
We performed ultrafast time-resolved near-infrared pump, resonant soft X-ray diffraction probe measurements to investigate the coupling between the photoexcited electronic system a…
Multiferroic properties of o-LuMnO controlled by b-axis strain
Y. W. Windsor, S. W. Huang, Y. Hu +7
Strain is a leading candidate for controlling magnetoelectric coupling in multiferroics. Here, we use x-ray diffraction to study the coupling between magnetic order and structural…
