Ferroelectricity induced by spin-dependent metal-ligand hybridization in BaCoGeO
H. Murakawa, Y. Onose, S. Miyahara +2
We have investigated the variation of induced ferroelectric polarization under magnetic field with various directions and magnitudes in a staggered antiferromagnet BaCoGeO$…
Electromagnons in the multiferroic state of perovskite manganites with symmetric-exchange striction
Y. Takahashi, S. Ishiwata, S. Miyahara +5
We have investigated electrically-active magnetic excitations (electromagnons) in perovskite manganites with the -type (up-up-down-down) spin structure by terahertz spectroscopy…
Terahertz time-domain spectroscopy of electromagnons in multiferroic perovskite manganites
N. Kida, Y. Takahashi, J. S. Lee +7
Recent spectroscopic studies at terahertz frequencies for a variety of multiferroics endowed with both ferroelectric and magnetic orders have revealed the possible emergence of a n…
The Truncated Polynomial Expansion Monte Carlo Method for Fermion Systems Coupled to Classical Fields: A Model Independent Implementation
G. Alvarez, C. Sen, N. Furukawa +2
A software library is presented for the polynomial expansion method (PEM) of the density of states (DOS) developed by two of the authors (N.F. and Y. M.). The library provides all…
Phase Separation in Electronic Models for Manganites
S. Yunoki, J. Hu, A. L. Malvezzi +3
The Kondo lattice Hamiltonian with ferromagnetic Hund's coupling as a model for manganites is investigated. The classical limit for the spin of the (localized) electrons i…
