“…Thus, HTSCs, CMR manganites, HLH perovskites demand three different approaches to achieve a proper morphology (Figure 1). For important devices utilizing these three perovskites, thin films, heterostructures or sandwiched structures have to be deposited (Zhang et al, 1996;Shiohara and Goodilin, 2000;Tretyakov and Goodilin, 2000;Tretyakov et al, 2004;Snaith and Hacke, 2018). CMR manganites (Pomerantseva et al, 2004) operate with a relative change of resistance under applied magnetic fields and this demands lateral transport of weak electrical currents while intergrain boundaries become highly important due to the effect of tunneling magnetoresistance (TMS).…”
