Abstract: Orbital degrees of freedom mediating an interaction between spin and lattice were predicted to raise strong magnetoelectric effect, i.e., to realize an efficient coupling between magnetic and ferroelectric orders. However, the effect of orbital fluctuations… read more here.

DOI: 10.7566/jpsj.87.073701
Abstract: We study superconductivity in a three-orbital model for f2 ions with the Γ3 crystalline electric field (CEF) ground state. An antiferromagnetic interaction between the Γ7 and Γ8 orbitals is introdu... read more here.
