Why does saturation magnetization (Ms) increase up to 2 mol% doping and then decrease with further doping, while coercivity continues to increase?

In Nd-doped CuO nanoparticles, the observed trend is that saturation magnetization (Mₛ) increases up to 2 mol% doping and then decreases, while coercivity (Hc) continues to increase.
