Abstract

We investigated the effect of Al doping in magnetic properties of the Y-type hexaferrite Ba $_{0.7}$ Sr $_{1.3}$ Zn $_{2}$ (Fe $_{1 - x}$ Al $_{x}$ ) $_{12}$ O $_{22}$ ( $0 \leq x \leq 0.12$ ), which exhibit field-induced magnetoelectric polarization. We find that Al doping increases the pitch of a spin helix and enhances $c$ -axis magnetization, stabilizing longitudinal conical phases. These conical phases eventually collapse at $x \geq$ 0.10. These results suggest that competitions between easy-axis and easy-plane anisotropy fields play a key role in generating stable magnetoelectric polarization in Y-type hexaferrites.
