These hydrogels show a dramatic change in their network structure and swelling behaviors in response to the external stimuli such as pH, temperature, electric field, and ion strength [1–3].

In this highly oriented structure the finely dispersed YBaCuO5 (211) grains act as flux pinning centres and increase the magnetic levitation forces [5].
