Non-equilibrium dynamics of spin-lattice coupling
Hiroki Ueda, Roman Mankowsky, Eugenio Paris +18
Interactions between the different degrees of freedom form the basis of many manifestations of intriguing physics in condensed matter. In this respect, quantifying the dynamics of…
High-field phase diagram of the chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4
Toshihiro Nomura, Yasuyuki Kato, Yukitoshi Motome +9
High-field phase diagram of a chiral-lattice antiferromagnet Sr(TiO)Cu4(PO4)4 is studied by means of the ultrasound, dielectric, and magnetocaloric-effect measurements. These exper…
Spin dynamics in the square-lattice cupola system Ba(TiO)Cu(PO)
Luc Testa, Peter Babkevich, Yasuyuki Kato +9
We report high-resolution single-crystal inelastic neutron scattering measurements on the spin-1/2 antiferromagnet Ba(TiO)Cu(PO). This material is formed from layers of…
Optical excitation of electromagnons in hexaferrite
Hiroki Ueda, Hoyoung Jang, Sae Hwan Chun +11
Understanding ultrafast magnetization dynamics on the microscopic level is of strong current interest due to the potential for applications in information storage. In recent years,…
Capacitive detection of magnetostriction, dielectric constant, and magneto-caloric effects in pulsed magnetic fields
Atsushi Miyake, Hiroyuki Mitamura, Shiro Kawachi +5
We report on the development of a capacitance measuring system which allows measurements of capacitance in pulsed magnetic fields up to 61~T. By using this system, magnetic-field r…
Domain switching and exchange bias control by electric field in multiferroic conical magnet MnGeO
Jonas K. H. Fischer, Hiroki Ueda, Tsuyoshi Kimura
The electric field effect on magnetism was examined in the multiferroic conical magnet MnGeO, which shows a strong coupling between ferromagnetic and ferroelectric order pa…
