摘要	We have investigated the low-temperature magnetism and spin-lattice coupling in (Bi(0.46)Na(0.46)Ba(0.08))TiO(3):Co in order to understand the magnetoelectric effect in such artificially synthesized dilute magnetic ferroelectrics. It is revealed that the as-prepared (Bi(0.46)Na(0.46)Ba(0.08))TiO(3):Co at Co content of 20%similar to 30% exhibits fascinating ferrimagnetism which is robust against magnetic field, the abnormal spin-lattice coupling characterized by a negative magnetostriction effect; and the suppressed magnetic moment with the temperature range of 30 K similar to 50 K is identified. These magnetic behaviours at low temperatures can be explained by the competition between the ferrimagnetic response and the magnetic moment suppression induced by the abnormal spin-lattice coupling effect. Finally, the ferroelectric and magnetodielectric properties are also discussed.
