“…Thus, the ME multiferroics are expected to be applicable for new electronic devices. Among a variety of ME multiferroics, hexaferrites are supposed to be the most promising materials for the device application, because they exhibit ferroelectricity associated with noncollinear magnetic orders in relatively low magnetic field and high temperature regions [3][4][5][6][7][8][9][10][11][12][13] . In the present study, we focus on a Y-type hexaferrite BaSrCo 2 Fe 11 AlO 22 (BSCo-FAO).…”

Magnetic structures and excitations in a multiferroic Y-type hexaferrite BaSrCo2Fe11AlO22

We have investigated magnetic orders and excitations in a Y-type hexaferrite BaSrCo 2 Fe 11 AlO 22 (BSCoFAO), which was reported to exhibit spin-driven ferroelectricity at room temperature [Hirose et al., Appl. Phys. Lett. 104, 022907 (2014)]. By means of magnetization, electric polarization and neutron diffraction measurements using single-crystal samples, we establish H-T magnetic phase diagram for magnetic field perpendicular to the c axis (H ⊥c). This system exhibits an alternating longitudinal conical (ALC) magnetic structure in the ground state, and it turns into a non-coplanar commensurate magnetic order with spin-driven ferroelectricity under H ⊥c. The field-induced ferroelectric phase remains as a metastable state after removing magnetic field below ∼ 250 K. This metastability is the key to understanding of magnetic-field-reversal of the spin-driven electric polarization in this system. Inelastic polarized neutron scattering measurements in the ALC phase reveal a magnetic excitation at around 7.5 meV, which is attributed to spin components oscillating in a plane perpendicular to the cone axis. This phason-like excitation is expected to be electric-field-active magnon, i.e., electromagnon excitation, in terms of the magnetostriction mechanism.

“…As x increases, the critical magnetic field for switching electric polarization is systematically reduced down to an extremely small 10 mT (100 G), and the ME susceptibility is greatly enhanced to reach a giant value of 2 9 10 4 ps m -1 at an optimum x = 0.08 [83]. When x = 1.0, the heliconical state collapses, due to competition between easy-axis and easy-plane anisotropies [83]. It is suggested that this giant magnetoelectricity occurs because the Al substitution progressively stabilises a longitudinal heliconical state, as opposed to the helical spin phase seen in unsubstituted BSZY (Fig.…”

The hexagonal ferrites, also known as hexaferrites, have become massively important materials commercially and technologically, accounting for the bulk of the total magnetic materials manufactured globally, and they have a multitude of uses and applications. As well as their use as permanent magnets, common applications are as magnetic recording and data storage materials, and as components in electrical devices, particularly those operating at microwave/GHz frequencies for mobile and wireless communications, electromagnetic wave absorbers for electromagnetic compatibility (EMC), radar absorbing materials (RAM) and stealth technologies. One of the most exciting recent developments has been the discovery of single phase magnetoelectric/multiferroic hexaferrites, IntroductionThe hexagonal ferrites are magnetic iron(III)-based oxides with a hexagonal crystal structure (Fig. 7.1), also known as hexaferrites. They have become massively important materials commercially and technologically, and hexaferrites are used in a multitude of applications, for example permanent magnets, electrical motors and transformers, actuators and sensors, information storage, mobile communications, transport, security, defence and aerospace [1]. M-type hexaferrites account for over 90 % of the total permanent magnetic materials
