Magnetic phase diagram copper metaborate CuB2O4 in magnetic field parallel c-axis: resonant, magnetic and magnetoelastic investigations
The magnetic phase diagram in a single crystal of copper metaborate CuB2O4 in a magnetic field parallel to a tetragonal axis c has been investigated. From the resonant, magnetic and magnetostrictive data the phase diagram of CuB2O4 on a plane “temperature magnetic field” is constructed. The magnetic incommensuratecommensurate phase transition is caused by the saturation of weak subsystem of cop...
متن کامل"Excitation of multiple phonon modes in copper metaborate CuB2O4 via non-resonant impulsive stimulated Raman scattering"
Copper metaborate CuB2O4 is a material with a unique crystallographic structure, space group 42m (Z=12), in which magnetic Cu ions occupy two types of nonequivalent positions 4b and 8d. Below the antiferromagnetic ordering at TN = 21 K this material demonstrates a very complicated magnetic phase diagram with commensurate and incommensurate phases [1]. This material also demonstrates very intere...
متن کاملCalculated chiral and magneto-electric dichroic signals for copper metaborate (CuB(2)O(4)) in an applied magnetic field.
Expressions for dichroic signals in terms of electron multipoles have been used to analyse optical data gathered on a crystal of copper metaborate in the presence of a magnetic field. Calculated signals comply with the established crystal and magnetic structures of CuB(2)O(4), and respect the global symmetries of parity-even and parity-odd dichroic signals in full. We have success in describing...
متن کاملRubidium metaborate, Rb3B3O6.
Rubidium metaborate, Rb3B3O6, was obtained by the reaction of Rb2CO3 and BN using a radiofrequency furnace at a maximum reaction temperature of 1173 K. The crystal structure has been determined by single-crystal X-ray diffraction. The space group is R3c, with all atoms positioned on a twofold axis (Wyckoff site 18e). The ionic compound is isotypic with Na3B3O6, K3B3O6 and Cs3B3O6.
متن کاملSpin - wave spectrum of copper metaborate in the commensurate phase 10 K < T < 21
We have investigated the spin-wave spectrum of copper metaborate, CuB 2 O 4 , by means of inelastic neutron scattering in the commensurate magnetic phase. We have found two branches of spin-wave excitations associated with the two magnetic sublattices Cu(A) and Cu(B), respectively. In the temperature regime 10K ≤ T ≤ 21K, where only the Cu(A) magnetic moments are ordered, the interaction betwee...
