Electric Field Control of Nonvolatile Four-State Magnetization at Room Temperature
Open accessAbstract
We find the realization of large converse magnetoelectric (ME) effects at room temperature in a magnetoelectric hexaferrite ${\mathrm{Ba}}_{0.52}{\mathrm{Sr}}_{2.48}{\mathrm{Co}}_{2}{\mathrm{Fe}}_{24}{\mathrm{O}}_{41}$ single crystal, in which rapid change of electric polarization in low magnetic fields (about 5 mT) is coined to a large ME susceptibility of $3200\text{ }\text{ }\mathrm{ps}/\mathrm{m}$. The modulation of magnetization then reaches up to $0.62{\ensuremath{\mu}}_{B}/\mathrm{f}.\mathrm{u}$. in an electric field of $1.14\text{ }\text{ }\mathrm{MV}/\mathrm{m}$. We find further that four ME states induced by different ME poling exhibit unique, nonvolatile magnetization versus electric field curves, which can be approximately described by an effective free energy with a distinct set of ME coefficients.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
