Antiferromagnetic interlayer coupling of (111)-oriented La0.67Sr0.33MnO3/SrRuO3 superlattices Project supported by the National Basic Research Program of China (Grant Nos. 2016YFA0300701, 2017YFA0206300, and 2017YFA0303601) and the National Natural Science Foundation of China (Grant Nos. 11520101002, 51590880, and 11674378). |
(a) Minor loops at 10 K under cooling field Hcool = ±4 T for (111)-oriented LSMO/SRO superlattices. (b) The temperature dependence of HEB with Hcool = −4 T. (c) The cooling field dependence of HEB at T = 10 K. Inset shows the hysteresis loop with Hcool = −4 T and −0.1 T. |
