Sinusoidal electromagnon in RMnO3: Indication of anomalous magnetoelectric coupling
Markku P. V. Stenberg, Rogério de Sousa
The optical spectra in the family of multiferroic manganites RMnO3 is a great puzzle. Current models can not explain the fact that two strong electromagnons are present in the non-…
Model for twin electromagnons and magnetically induced oscillatory polarization in multiferroic RMnO
Markku P. V. Stenberg, Rogerio de Sousa
We propose a model for the pair of electromagnon excitations observed in the class of multiferroic materials {\it R}MnO ({\it R} is a rare-earth ion). The model is based on a h…
Response functions of an artificial Anderson atom in the atomic limit
Ari T. Alastalo, Markku P. V. Stenberg, Martti M. Salomaa
We consider the spin and pseudospin (charge) response functions of the exactly soluble Anderson atom model. We demonstrate, in particular, that a deviation from the magnetic Curie-…
