Investigation of spin excitations and charge order in bulk crystals of the infinite-layer nickelate LaNiO
S. Hayashida, V. Sundaramurthy, P. Puphal +10
Recent x-ray spectroscopic studies have revealed spin excitations and charge density waves in thin films of infinite-layer (IL) nickelates. However, clarifying whether the origin o…
Dielectric relaxation by quantum critical magnons
Daniel Flavián, Pavel A. Volkov, Shohei Hayashida +4
We report the experimental observation of dielectric relaxation by quantum critical magnons. Complex capacitance measurements reveal a dissipative feature with a temperature-depend…
Nontrivial temperature dependence of magnetic anisotropy in multiferroics BaMnGeO
Shunsuke Hasegawa, Shohei Hayashida, Shinichiro Asai +3
We measured the temperature dependences of the static magnetization and the spin excitation in a square-lattice multiferroics BaMnGeO. An anisotropy gap of the observed…
Anomalous spin waves in CsFeCl and RbFeCl
L. Stoppel, S. Hayashida, Z. Yan +2
We investigate magnetic excitations in the easy-plan-type triangular antiferromagnets CsFeCl and RbFeCl through a combination of inelastic neutron scattering meas…
Inelastic neutron scattering determination of the spin Hamiltonian for BaCdVO(PO)
V. K. Bhartiya, S. Hayashida, K. Yu. Povarov +4
Single crystal inelastic neutron scattering is used to study spin wave excitations in the fully polarized state of the frustrated quantum ferro-antiferromagnet BaCdVO(PO).…
Magnetic order in the chemically-substituted frustrated antiferromagnet CsCrF
Shohei Hayashida, Masato Hagihala, Maxim Avdeev +3
The effect of chemical substitution on the ground state of the geometrically frustrated antiferromagnet CsCrF has been investigated through a neutron powder diffraction experim…
