Experimental evidence of Tc enhancement above 50 K and diode and paramagnetic-Meissner effects, in Nickelate films on highly reduced $SrTi{O}_3$

Anna Eyal, Gad Koren

Since the discovery of superconductivity in nickelate thin films in 2019, the quest for enhancing their ${\mathrm{T}}_{\mathrm{c}}$ has been ongoing. Here we provide experimental evide…
