The effect of the rare-earth ion Er 3+ , which has a large orbital contribution to magnetic moment, were studied phase transitions and transformations 2D nanoregions separation in ErMn 2 O 5 multiferroic. These are semiconductor heterostructures (superlattices) formed due self-organization processes matrix. Significant ions, moments rigidly oriented along c axis crystal, on dynamics, heat capac...

This chapter gives a detailed expedition of multiferroic materials, from their inception as theoretical interest to current status centre global research effort set influence technology and moreover, it commences with the introduction an overview materials along classification. After conferring extensive advancement in field multiferroics, multifunctional applications multiferroics is taken int...

Layered van der Waals materials have risen as powerful platforms to artificially engineer correlated states of matter. Here we show the emergence a multiferroic order in twisted dichalcogenide bilayer superlattice at quarter-filling. We that competition between Coulomb interactions leads simultaneous ferrimagnetic and ferroelectric orders. derive magnetoelectric coupling for this system, which ...

Magnetic excitations in multiferroic materials accompany electric polarization, known as electromagnons. The authors develop here a general framework to study polarization and nonlinear optical responses of noncentrosymmetric magnets based on spin models. They theoretically demonstrate the excitation electromagnon-induced dc current generation (i.e., photovoltaic effect) from so-called shift me...

Multiferroics are a unique class of materials where magnetic and ferroelectric orders coexist. The research on multiferroics contributes significantly to the fundamental understanding strong correlations between different material degrees freedom provides an energy-efficient route toward electrical control magnetism. While multiple ABO3 oxide perovskites have been identified as being multiferro...

The phase diagram of quarter-hole-doped perovskite manganites is investigated using the double-exchange model. An exotic striped type-II multiferroic phase, where 25% of the nearest-neighbor spin couplings are orthogonal to each other, is found in the narrow-bandwidth region. Comparing with the spiral-spin ordering phase of undoped manganites, the multiferroic Curie temperature of the new phase...
