Fingerprint of dynamical charge/spin correlations in the tunneling spectra of colossal magnetoresistive manganites

S. Seiro, Y. Fasano, I. Maggio-Aprile +3

We present temperature-dependent scanning tunneling spectroscopy measurements on $L{a}_{1-x}C{a}_{x}M{O}_3$ ($x\sim 0.33$) films with different degrees of biaxial strain. A depletion in…
