Short range magnetic exchange interaction favors ferroelectricity.
Multiferroics, where two or more ferroic order parameters coexist, is one of the hottest fields in condensed matter physics and materials science. To search multiferroics, currently most researches are focused on frustrated magnets, which usually have complicated magnetic structure and low magnetic ordering temperature. Here, we argue that actually simple interatomic magnetic exchange interacti...

متن کاملCombining long-range configuration interaction with short-range density functionals
A density functional for short-range electron–electron interaction recently developed by one of us, has been implemented into a multi-reference configuration-interaction code with explicit treatment of long-range interaction only. Possible Ž . Ž advantages of such an approach are discussed, using as examples some closed-shell atoms Be, Ne and diatomics H , Li , 2 2 . C , N , F . q 1997 Publishe...
متن کاملRepulsive short-range three-nucleon interaction.
The three nucleon interaction that arises from pion and the effective scalar and vector meson exchange components of the nucleon-nucleon interaction is constructed and shown to be repulsive. Using several wavefunction models we show that this interaction reduces the calculated binding energy of the trinucleons by about 200 keV. The contributions of intermediate N(1440) resonances to this three ...
