Abstract Magnetoelectric multiferroics are key materials for next-generation spintronic devices due to their entangled magnetic and ferroelectric properties. Spiral multiferroics possess ferroelectric polarization and are particularly promising for electric control of magnetism and magnetic control of ferroelectricity. In this work. we uncover long-period incommensurate states charact... https://www.seisukeknifes.shop/product-category/peeler/
