Paper Abstract

We present the first findings of the magnetic susceptibility measurements that identify the spin polarons formed by the exchange interaction of the Yb-related centers through the shallow donor electrons in InP:Yb. The spin polarons are found to be localized on the clusters that consist of the Yb-related centers because of inhomogeneous distribution of dopants during the crystal growth. The influence of the internal magnetic fields created by spin polarons on the photoluminescence assigned to the internal 4f-4f transitions 2F5/2 yields 2F7/2 of Yb3+ (4fd3) ions is also discussed. Zeeman measurements that are in a good agreement with the photoluminescence spectroscopy data further support the model suggested for spin polarons.
