Introduction Magnetoelectric multiferroic materials that are simultaneously ferroelectric and ferromagnetic, have attracted great interest in the past few years due to their potential technological applications and the fascinating fundamental physics [1-3].
However, it is generally difficult to find materials that are magnetic as well as ferroelectric, since ferroelectricity occurs when the metal ions have empty d-orbitals whereas magnetism occurs in materials containing cations with partially filled d-orbitals.
Experimental procedure The BFO nanoislands were grown by a chemical self-assembly method using bismuth oxide and iron nitrate as starting materials.

Absorber, a key component affecting the LiBr absorption refrigerator performance, absorbs continuously low temperature vapor and pressure from the evaporator to ensure that the evaporator works all along at a lower pressure and that the refrigerator work stably，and its structure and performance determine the overall system size and efficiency.
To improve efficiency and reduce material, a host of countries have studied new high-efficiency absorbers, and in this regard they have produced some new findings.
