Multiferroics: Different ways to combine magnetism and ferroelectricity

“…Apparently the only exceptions in the stoichiometric (not mixed) perovskites are BiFeO 3 [11] and BiMnO 3 [19], and may be the recently synthesized PbVO 3 [20]. But even these examples in fact do not violate this general `` exclusion'' rule for perovskites: ferroelectricity in them apparently has a different source than in most of the FE of this class, such as BaTiO 3 This was probably realized by the people working in this field [1,2] already long ago, but not stressed in an apparent way and not explained. This question was raised in 1999 during the workshop on quantum magnetism at the ITP in Santa Barbara, see also [21], and was largely elaborated by N.Spaldin (N.Hill) [22].…”

“…The first route was taken by the Russian groups [1,2] Concluding this section, I want to stress once again that all the arguments presented above are applicable to systems in which TM ions are responsible for FE. Thus e.g.…”

“…The attempts to combine in one system both the (ferro)magnetic and ferroelectric (FE) properties started in 1960's, predominantly by two groups in then the Soviet Union: the group of Smolenskii in St.Petersburg (then Leningrad) [1] and by Venevtsev in Moscow [2]. Materials combining these different "ferroic" [3] properties were later on called "multiferroics" [4].…”

“…This special class of materials is named multiferroics and was introduced first in the 1960's by Smolenskii and Venevtsev [1,2]. In 1994 the interest in this topic has been renewed by H. Schmid [3], who introduced first the synomym multiferroics.…”

“…In view of this, PFN and PFW are the outstanding candidates due to the origin of ME coupling in them is a d -orbital mechanism [1][2][3][4][5][6]. By making the solid solution of PFN and PFW (PFN 1-x -PFW x ), the effective T N and T C can be tuned to RT or near RT, leading to RT multiferroics.…”
