Field-induced ferroelectric and commensurate spin state in mutiferroic HoMn${}_2$O${}_5$

H. Kimura, Y. Kamada, Y. Noda +3

Neutron diffraction measurements under high magnetic fields have been performed for the multiferroic compound HoMn${}_2$O${}_5$. At zero field, high-temperature incommensurate magn…
