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 scaling of ultrafast angular momentum transfer in 4 antiferromagnets
Y. W. Windsor, S-E. Lee, D. Zahn +11
Ultrafast manipulation of the magnetic state of matter bears great potential for future information technologies. While demagnetisation in ferromagnets is governed by dissipation o…
Coherent Modulation of Quasiparticle Scattering Rates in a Photoexcited Charge-Density-Wave System
J. Maklar, M. Schüler, Y. W. Windsor +8
We present a complementary experimental and theoretical investigation of relaxation dynamics in the charge-density-wave (CDW) system TbTe after ultrafast optical excitation. Us…
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…
Nonequilibrium Charge-Density-Wave Order Beyond the Thermal Limit
J. Maklar, Y. W. Windsor, C. W. Nicholson +17
The interaction of many-body systems with intense light pulses may lead to novel emergent phenomena far from equilibrium. Recent discoveries, such as the optical enhancement of the…
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…
Lattice dynamics and ultrafast energy flow between electrons, spins, and phonons in a 3d ferromagnet
Daniela Zahn, Florian Jakobs, Yoav William Windsor +8
The ultrafast dynamics of magnetic order in a ferromagnet are governed by the interplay between electronic, magnetic and lattice degrees of freedom. In order to obtain a microscopi…
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…
