| Abstract: | We have investigated the influence of different annealing conditions on the magnetic properties on the single crystals of double‐perovskite Y2CoMnO6. The ferromagnetic moment along the c‐axis with the large magnetic coercivity and high squareness ratio was observed. Particularly, in the quenched specimen, the magnetic functionality has been greatly improved compared to that of the as‐grown crystal. The magnetic coercivity and maximum energy product have been increased by ～120% and ～50%, respectively, by comprising substantial disorders and defects. Our result renders an efficient route to improve the magnetic functionality in mixed‐valent magnets. (© 2015 WILEY‐VCH Verlag GmbH &Co. KGaA, Weinheim) |
