(a,b) Magnetic field dependences of magnetization of SCMO23 and SCMO100 samples at T = 10 K measured after FC. Insets show a low field part of hysteresis loops on the extended scale. (c) Size dependence of spontaneous magnetization M0 and magnetization MS in H = 15 kOe at T = 10 K. (d) Coercive field of SCMO samples as a function of the particle size. Solid line is linear fit to the expression HC = a + b/D. |
