The effect of lattice distortion and orbital mixing on the optical and magnetic properties of cubic RMnO$sub3$ (R = La, Pr, Nd, Gd, Tb)

We investigated the $ab$-plane absorption spectra of $R$MnO ($R$ = La, Pr, Nd, Gd, and Tb) thin films. As the $R$-ion size decreases, we observed a drastic suppression of th…
