Magnetic phase diagram and spin Hamiltonian of antiferromagnet CsCoI
S. D. Nabi, L. Facheris, V. Romerio +12
We report comprehensive thermodynamic and neutron scattering measurements on the = 3/2 antiferromagnet CsCoI, a member of the thoroughly studied family of frustrated ma…
Magnetic field-induced phases and spin Hamiltonian in Cs2CoBr4
L. Facheris, S. D. Nabi, K. Yu. Povarov +12
Magnetic structures and spin excitations are studied across the phase diagram of the geometrically frustrated S = 3/2 quantum antiferromagnet Cs2CoBr4 in magnetic fields applied al…
Confinement of fractional excitations in a triangular lattice antiferromagnet
L. Facheris, S. D. Nabi, A. Glezer Moshe +6
High-resolution neutron and THz spectroscopies are used to study the magnetic excitation spectrum of CsCoBr, a distorted-triangular-lattice antiferromagnet with nearly XY-t…
Spin Density Wave versus Fractional Magnetization Plateau in a Triangular Antiferromagnet
L. Facheris, K. Yu. Povarov, S. D. Nabi +7
We report an excellent realization of the highly non-classical incommensurate spin-density wave (SDW) state in the quantum frustrated antiferromagnetic insulator CsCoBr. In…
Finite-temperature dynamics and the role of disorder in nearly critical Ni(ClBr)4SC(NH)
L. Facheris, D. Blosser, K. Yu. Povarov +3
Inelastic neutron scattering is used to investigate the temperature dependence of spin correlations in the 3-dimensional XY antiferromagnet Ni(ClBr)4SC(NH$_2…
Magnetization plateaux cascade in the frustrated quantum antiferromagnet CsCoBr
K. Yu. Povarov, L. Facheris, S. Velja +4
We have found an unusual competition of two frustration mechanisms in the 2D quantum antiferromagnet CsCoBr. The key actors are the alternation of single-ion planar anisotr…
Miniature capacitive Faraday force magnetometer for magnetization measurements at low temperatures and high magnetic fields
Dominic Blosser, Leonardo Facheris, Andrey Zheludev
A Faraday force magnetometer is presented for measurements of magnetization at temperatures down to 100~mK and in magnetic fields up to 14~T. The specimen is mounted on a flexible…
